It should be noted that, although not illustrating herein, but synchronizing signal can be configured with downlink subframe (Synchronization Signals), physical broadcast information channel, downlink reference signal (RS：Reference Signal, Downlink reference signals).As downlink reference signal, exist by being sent out with PDCCH identicals Peculiar reference signal (the CRS of cell that sending end mouth is sent：Cell-specific RS), for measure channel state information (CSI： Channel State Information) channel state information reference signals (CSI-RS), by identical with a part of PDSCH Sending port send the peculiar reference signal (URS of terminal：UE-specific RS), by with EPDCCH identical sending ports Demodulation reference signal (the DMRS of transmission：Demodulation RS) etc..In addition it is also possible to it is the carrier wave for being not configured with CRS. Now, the part transmission with CRS can be inserted in a part of subframe (for example, first in radio frames and the 6th subframe) Signal identical signal (the referred to as synchronous letter of extension corresponding to port (such as only sending port 0) or whole sending ports Number), as time and/or the tracking signal of frequency.In addition, by the end sent with a part of PDSCH identicals sending port Peculiar reference signal is held to be also referred to as establishing the peculiar reference signal of terminal associated or DMRS with PDSCH.In addition, by with EPDCCH The demodulation reference signal that identical sending port is sent is also referred to as establishing the DMRS associated with EPDCCH.

It should be noted that, although not illustrating herein, but detection signal can be configured with downlink subframe (DS：Discovery Signal).Terminal sets (configuration) DMTC (Discovery based on the parameter configured by RRC signaling signals measurement timing configuration：It was found that signal measurement timing configured).DMTC Occasion (DMTC occasions) is 6 milliseconds, is made up of continuous 6 subframes.Furthermore, it is assumed that being the terminal not to outside DMTC Occasion Subframe sends DS.

It should be noted that detection signal (DS：Discovery Signal) it can both be referred to as DRS (Discovery Reference Signal：It was found that reference signal), Initial Signal (initial signal) can also be referred to as, can also quilt Referred to as reservation signal (Reservation Signal).

It should be noted that detection signal (DS：Discovery Signal) it both may be embodied in Initial Signal In (initial signal), it can also be included in reservation signal (Reservation Signal).It should be noted that Initial Signal (initial signal) and/or reservation signal (Reservation Signal) are preferably sent by LAA cells.

In a certain cell, DS (DS Occasion) by continuous specified quantity subframe period (during DS) structure Into.The specified quantity is in FDD (Frame structure type1：Frame structure Class1) in be 1 to 5, in TDD (Frame structure type2：Frame structure type 2) in be 2 to 5.The specified quantity is configured by RRC signaling.In addition, DS Period or its configuration are also referred to as DMTC (Discovery signals measurement timing configuration). It is assumed that the DS of terminal is sent out the parameter dmtc-Periodicity of each signal deployment by the RRC subframes configured Send and (mapping, produce).In addition, in downlink subframe, terminal assumes the DS formed comprising signals below be present.

(1) in the DwPTS of all downlink subframes during the DS and all special subframes, antenna port 0 CRS。

(2) in fdd, the PSS in the initial subframe during the DS.In TDD, in the 2nd subframe during the DS PSS.

(3) SSS in the initial subframe during the DS.

(4) the non-zero power CSI-RS in the subframe more than zero during the DS.Non-zero power CSI-RS passes through RRS Signaling configure.

Terminal is measured based on the DS configured.The measurement uses the non-zero power in CRS or DS in DS CSI-RS is carried out.In addition, in the configuration relevant with DS, multiple non-zero power CSI-RS can be configured.

With the synchronization (time synchronization) of the time domain of downlink, the synchronization of the frequency of downlink (frequency synchronization), determination (cell/transmissionpoint of cell/sending point Identification), RSRP measurement (RSRP measurement), RSRQ measurement (RSRQ measurement), Rssi measurement (RSSI measurement), terminal installation 1 geographical position measurement (UE Positioning), CSI survey For the purpose of measuring various uses such as (CSI measurement), DS is sent from base station apparatus.DS can be as base station apparatus The signal that open mode and closed mode (state of activation and deactivation status of cell) are supported.DS, which can be used as, to be used for The base station apparatus of open mode and/or closed mode (cell of state of activation and/or deactivation status) is entered for terminal installation The signal of row detection.It should be noted that can also be by the measurement of measurement (RSRP measurement), RSRQ with RSRP The measurement of (RSRQ measurement) and/or rssi measurement (RSSI measurement) association is referred to as RRM measurements (Radio Resource Management measurement：RRM measures).

As an example, DS is made up of PSS, SSS and CRS.When contained PSS and SSS are likely to be used in DS Between synchronization, Frequency Synchronization, the determination of cell and the determination of sending point.In DS contained CRS be likely to be used for RSRP measurement, RSRQ measurement and CSI measurement.As another example, DS is made up of PSS, SSS and CSI-RS.Contained by DS PSS and SSS is likely to be used for time synchronized, Frequency Synchronization, the determination of cell and the determination of sending point.Contained by DS CSI-RS is likely to be used for the determination of sending point, RSRP measurement, RSRQ measurement and CSI measurement.It should be noted that The DS being made up of multiple signals can also be referred to as detection burst (Discovery burst).It should be noted that carry out RSRP Measurement and/or the RSRQ reference signal of measurement can also be referred to as DS.

Terminal is measured based on the DS configured.DS can use the signal (nothing of each structure respectively according to purpose Line resource).For example, in time domain, the synchronization of frequency domain and cell identification, RRM measurements (RSRP, RSRQ and/or rssi measurement) For the signal used, it can be carried out using the signal of different structure.That is terminal installation 1 can use the first signal (the first DS) carries out the synchronization of time domain, frequency domain, and cell identification is carried out using secondary signal (the 2nd DS), uses the 3rd signal (the Three DS) carry out RSRP and/or RSRQ measurements.Further, it is also possible to using the first signal and secondary signal carry out time domain, frequency domain it is same Step and cell identification, RRM measurements (RSRP, RSRQ and/or rssi measurement) are carried out using the 3rd signal.

It should be noted that the DS in LBT cell (such as LAA cells) etc. is needed to be preferably based on LBT to send.That is, Before sending DS, the jamming power of the frequency (is done using a certain frequency (component carrier, cell) in a certain base station or terminal Disturb signal, receiving power, reception signal, noise power, noise signal) etc. measure (detection), be empty to the frequency thus Not busy state (blank state, congestion state, Presence, Occupied) or busy condition (non-blank state, non-congested shape State, Absence, Clear) it is identified and (detection, assumes, determines).The feelings that the frequency is idle condition are being identified as based on LBT Under condition, the regulation timing that the LAA cells can be on that frequency sends DS.It is busy condition being identified as the frequency based on LBT In the case of, the regulation timing of the LAA cells not on that frequency sends DS.

It should be noted that in DS and terminal installation are sent based on LBT and considers the subframe in DMTC occasion DS send in the case of, in the subframe preferably in DMTC occasion carry out DS transmissions.That is, base station apparatus is preferably carried out LBT so that DS transmissions can be carried out in the subframe in DMTC occasion.

(Class1 DS transmissions) is sent it should be noted that can be sent the DS for being not based on LBT and be referred to as Type1DS, by base Sent in LBT DS and be referred to as Type2DS transmissions (type 2DS transmissions).It should be noted that it can also will be not based on LBT DS Send and be referred to as the first DS transmissions, the DS based on LBT is sent into referred to as the 2nd DS sends.

DS and DMTC in LAA cells can be set to identical with the DS in FDD and DMTC.For example, in LAA cells, With being any one in 1 to 5 in the same manner as FDD during DS, PSS be present in the initial subframe during the DS.Need what is illustrated It is that the DS in LAA cells can also be configured to different from the DS in conventional cell.For example, the DS in LAA cells does not include CRS. In addition, the DS in LAA cells includes the PSS and SSS that can be shifted in a frequency direction.

In addition, in LAA cells, control signal and/or control channel comprising control information can pass through DS Occasion Subframe in interior subframe or DMTC Occasion is transmitted.The control information can include the letter relevant with LAA cells Breath.For example, the control information be with the frequency in the LAA cells, load, Congestion Level SPCC, interference, transmit power, channel it is special Having time and/or the relevant information of situation for sending the related buffering area of data.

In addition, the control signal and/or control channel can be demodulated or detected by the DMRS in DS Occasion. That is, control signal and/or control channel is transmitted by the antenna port for sending the DMRS in DS Occasion.Tool For body, the DMRS in DS Occasion is to establish the DMRS (demodulation references associated with the control signal and/or control channel Signal), can with establish the DMRS that associate with PDSCH or EPDCCH in the same manner as form.

In addition, scramble sequence used in establishing the DMRS associated with the control signal and/or control channel can also give birth to It is different as scramble sequence used in the DMRS associated from PDSCH or EPDCCH foundation.Here, scrambled used in DMRS Sequence is generated using the value calculated based on time-gap number (subframe number), the first parameter and the second parameter as initial value. For example, in scramble sequence used in establishing the DMRS associated with PDSCH, the first parameter is by cell identifier (cell ID) Or the value of upper-layer configured, the second parameter are 0 or 1 provided by DCI.In addition, the second parameter is by DCI in the case where not provided, It is fixed as 0.In scramble sequence used in establishing the DMRS associated with EPDCCH, the first parameter is to be directed to each EPDCCH collection The value by upper-layer configured is closed, the second parameter is fixed as 2.

Established with the control signal and/or control channel in scramble sequence used in the DMRS associated, the first parameter The value by upper-layer configured, be the LAA cells cell identifier or with the non-zero power CSI-RS in DS Occasion Corresponding cell identifier.Established with the control signal and/or control channel in scramble sequence used in the DMRS associated, Second parameter is to be fixed as the value of setting or is value by upper-layer configured.The situation of setting is fixed as in the second parameter Under, establish the DMRS associated with PDSCH or EPDCCH used in the second parameter for using in scramble sequence again it is 0,1 Or the used in any value in 2, or scramble sequence used in with PDSCH or EPDCCH establishing the DMRS associated The different value of two parameters (such as 3).In the case where the second parameter is by upper-layer configured, the second parameter can configure arbitrary value, such as The distinctive value of operator can be configured.

In addition, the control signal and/or control channel can be demodulated or detected by the CRS in DS Occasion. That is, control signal and/or control channel is transmitted by the antenna port for sending the CRS in DS Occasion.Need Illustrate, scramble sequence used in the CRS in DS Occasion can be based on building with the control signal and/or control channel The first parameter illustrated in scramble sequence used in the DMRS of association and/or the second parameter are found to generate.

Then, the details of the measurement to physical layer illustrate.Terminal installation carries out the survey for the physical layer reported to upper strata Amount.In the measurement of physical layer, RSRP (Reference Signal Received Power be present：Reference signal receives work( Rate), RSSI (Received Signal Strength Indicator：Received signal strength indicator), RSRQ (Reference Signal Received Quality：Reference Signal Received Quality) etc..It should be noted that can also be by the measurement with RSRP (RSRP measurement), RSRQ measurement (RSRQ measurement) and/or rssi measurement (RSSI Measurement) measurement of association is referred to as RRM measurements (Radio Resource Management measurement：Wirelessly Resource management measures).

Then, RSRP details are illustrated.RSRP is defined as the receiving power of reference signal.RSRQ is defined as referring to The quality of reception of signal.

A RSRP example is illustrated.

It should be noted that in the measurement frequency bandwidth considered and for determining CSI- by terminal installation The quantity of resource element in RSRP measurement period depends on the installation with conditional terminal installation.Need what is illustrated It is that the limitation needs the necessary condition of measurement accuracy corresponding to satisfaction.

DS Measurement bandwidth can be configured using top signaling.

In DS cell is sent based on LBT, terminal installation is preferably based in the subframe in configured DS Occasion The CSI-RS and/or CRS and/or PSS and/or SSS that are configured to measure DS included in the measurement frequency bandwidth considered And/or the 2nd SSS (use the time different from conventional SSS and/or synchronizing signal that frequency is sent) come measure RSRP and/or RSRQ and/or RSSI and/or CSI-RSRP and/or CSI-RSRQ and/or CSI-RSSI.And then the RSRP to measuring and/or RSRQ and/or RSSI and/or CSI-RSRP and/or CSI-RSRQ and/or CSI-RSSI etc. carries out the evaluation of reporting criteria.So Afterwards, after being judged as needing reporting measurements by the evaluation of reporting criteria, terminal installation is sent by wave point and measured Report information (measurement report message).It should be noted that the configuration of reporting criteria is provided by RRC signaling.

It should be noted that the DS in LBT cell (such as LAA cells) etc. is needed to be preferably based on LBT to send.Terminal Device carries out the measurement based on DS within the physical layer, and (the RSRP measurements based on DS, the RSRQ based on DS are measured and/or based on DS Rssi measurement etc.) when, LBT is not based in the subframe for considering to send DS in terminal installation sometimes and sends DS.That is, may Situations below occurs：It is actual in the subframe for considering to send DS in terminal installation not send DS.It should be noted that consider The subframe that DS is sent in terminal installation is preferably the subframe in DMTC occasion.

In DS cell is sent based on LBT, terminal installation is carried out based on DS measurement (based on DS's within the physical layer RSRP is measured and/or the RSRQ measurements based on DS and/or rssi measurement based on DS etc.) when, if to based on considering in terminal The DS actually sent in DS subframe measurement result is sent in device and based on the subframe for considering the transmission DS in terminal installation The measurement result for the DS that middle reality is not sent is averaged, then terminal installation can not be measured correctly.That is, terminal installation without Method carries out the measurement based on the DS actually sent.That is, terminal installation can not be based only upon the DS actually sent RSRP measurement, And/or it is based only upon the DS actually sent RSRQ measurements and/or is based only upon the DS actually sent rssi measurement.

It should be noted that in DS cell is sent based on LBT, it can also notify whether be based on LBT to terminal installation It actually have sent DS.For example, DS clearly can be have sent based on LBT is actual to terminal installation notice.For example, it is also possible to clearly Ground does not actually send DS to terminal installation notice based on LBT.It should be noted that represent based on LBT it is actual have sent DS and/or Do not sent actually based on LBT DS notice preferably using mandate cell (licensed cell) (not being the cell of LAA cells) come Carry out.It should be noted that represent preferably to make based on the actual notices that have sent DS and/or do not send DS actually based on LBT of LBT With with send the different cell of the LAA cells that associate from the DS to carry out.It should be noted that represent based on the actual transmissions of LBT DS and/or do not send DS notice actually based on LBT and preferably use the LAA cells associated with DS transmissions to carry out.Need Illustrate, represent preferably to use physical layer based on the actual notices that have sent DS and/or do not send DS actually based on LBT of LBT In signal carry out.It should be noted that represent based on LBT it is actual have sent DS and/or based on LBT actually do not send DS's Notice is preferably carried out using the subframe outside DMTC occasion.

And then be notified based on LBT is actual have sent DS in the case of, preferably by based on the DS measurement result report Give (terminal installation) upper strata.And then be notified based on LBT actually do not send DS in the case of, will not preferably be based on the DS Measurement result report to (terminal installation) upper strata and abandon.

And then can also to being notified based on the actual measurement results based on the DS that have sent in the case of DS of LBT and It is notified both measurement results based on the DS in the case of not sending DS based on LBT reality to be kept, according to measurement The triggering of report sends any of which.

It should be noted that in DS cell is sent based on LBT, it can also notify whether be based on LBT to terminal installation It actually have sent DS.

It should be noted that in DS cell is sent based on LBT, can also be determined whether to be based on LBT by terminal installation It actually have sent DS.For example, terminal installation carries out the measurement based on DS within the physical layer (is thought of as sending DS resource element The measurement of the power level of element and/or the RSRP measurements described later based on DS, the RSRQ measurements based on DS, the RSSI based on DS Measurement etc.), by measurement result, with threshold value compared with and measurement result is more than in the case of threshold value, terminal installation preferably judges To have sent DS based on LBT is actual.

And then be determined as based on LBT is actual have sent DS in the case of, preferably by based on the DS measurement result report Give (terminal installation) upper strata.And then in the case where being judged to actually not sending DS based on LBT, it will not preferably be based on the DS Measurement result report to (terminal installation) upper strata and abandon.It should be noted that threshold value preferably by the signaling on upper strata or Physical layer signals (configuration) to terminal installation.

And then can also to be judged as based on the actual measurement results based on the DS that have sent in the case of DS of LBT, Kept with being judged as not sending both measurement results based on the DS in the case of DS actually based on LBT, according to The value for triggering to send any of which or calculate based on any of which of measurement report.

Then, the mechanism of the measured value to being measured to upper strata report by terminal installation illustrates.

Measurement model is illustrated.Figure 11 is the figure for an example for representing measurement model.

Measurement portion 1301 is configured to comprising first layer filtering part 13011, third layer filtering part 13012 and report The evaluation section 13013 of benchmark.It should be noted that measurement portion 1301 can also be configured to comprising at acceptance division 105 and upper strata The part of functions in reason portion 101.Specifically, it is configured to：First layer filtering part 13011 is included in acceptance division 105, the The evaluation 13013 of three layers of filtering part 13012 and reporting criteria is included in upper strata processing unit 101.

(filtering of Layer 1) portion 13011 is filtered from the measured value (sample) of physical layer input by first layer to implement Filtering.First layer the filtering part 13011 such as average value of the multiple input values of application, weighted average, follow the flat of the characteristic of channel Average etc., other filtering methods can also be applied.The measured value reported from first layer is defeated after first layer filtering part 13011 Enter to third layer.The measured value for being input to third layer filtering (filtering of Layer 3) portion 13012 is carried out filtering.3rd The configuration of layer filtering is provided by RRC signaling.The interval for being filtered and being reported by third layer filtering part 13012 and the survey inputted Amount interval is identical.In the evaluation section 13013 of reporting criteria, the report of measured value whether is needed to check to actual.Evaluation Based on more than one measurement procedure.Comparison between for example, different measured values etc..Terminal installation is at least reported every time The evaluation of reporting criteria is carried out during new measurement result.The configuration of reporting criteria is provided by RRC signaling.Passing through reporting criteria Evaluation is judged as after needing reporting measurements that (measurement report disappears terminal installation via wave point transmission measurement report information Breath).

Passing through third layer filtering part from the measurement result of first layer filtering part 13011 (that is physical layer) output When 13012 (that is in report of evaluation or the measurement of reporting criteria before use), it is implemented such that and has used formula (1) Filtering.

(formula 1)

F_n=(1-α) × F_n-1+α×M_n

Here, M_nFor the newest reception measurement result (that is measurement result at Figure 11 point B) from physical layer. In addition, F_nAfter the renewal that is used in the report for being evaluation or the measurement of reporting criteria, filtering measurement result (that is Figure 11 point C or the measurement result at C ' places).In addition, F_n-1Be it is previously filtered obtained by measurement result ((have that is past For body, when measuring for (n-1)th time in so far the n time measurement comprising this measurement) Figure 11 point C or C ' that measure The measurement result at place).It should be noted that F₀It is arranged to receive M during the initial measurement result from physical layer₁.So Afterwards, α is to calculate F_nWhen represent past measurement result and newest measurement result ratio parameter, be expressed as α=1/2^(k ^/4).It should be noted that k is to configure (being configured to upper-layer parameters) that receives, for corresponding measurement amount by measurement amount Filter factor (filterCoefficientRSRP, filterCoefficientRSRQ, filterCoefficientCSI- RSRP etc.).For example, point C or C ' places in Figure 11, in order to obtain RSRP measurement result, using the filtering system relevant with RSRP Number (filterCoefficientRSRP).In addition, point C or C ' places in Figure 11, in order to obtain RSRQ measurement result, application The filter factor (filterCoefficientRSRQ) relevant with RSRQ.That is the filter factor applied can be according to survey The species of amount and it is different.But in the case of filter factor corresponding to not configured via top signaling, terminal installation also may be used To obtain Figure 11 point C or C ' places measurement result using default value.It should be noted that can be by third layer filtering part The filter factor applied in 13012 is referred to as third layer filter factor.

In terminal installation, filtered by application, even if being different input intervals, also retention time property.Filtering system Number k is assumed to and the 200ms identical sampling intervals.

In the case where k is arranged to 0, third layer is not applied to filter.That is in the case where k is arranged to 0, eventually End device can not obtain the measurement result for applying third layer filtering.

Filter and carried out in the domain identical domain used in the evaluation or the report of measurement with reporting criteria.For example, for Measurement with log characteristic can apply the filtering with log characteristic.

Being input to the interval of filtering part can freely configure (that is, it is possible to depending on installation).

Obtain F_nWhen, in M_nAnd F_n-1In the case of being the measurement result obtained using different measuring methods, it can reset F_n-1.For example, in F_n-1It is measurement result, the M for the RSPP for being directed to CRS_nIt is the situation for CSI-RS RSRP measurement result In the case of being changed etc. measurement object, F can be reset_n-1.That is, it is possible to only to F_nUsing M_n(that is F_n=M_n)。

Third layer filter factor is specified using measurement amount configuration (quantityConfig).Third layer filter factor is used for Provide the ratio between newest measurement result and past filtered measurement results (ratio) (that is for calculating α).Need what is illustrated It is that third layer filtering can be filtered referred to as.

Then, the configuration side of the third layer filter factor (L3 filtering coefficient) of present embodiment is shown One example of method.

Corresponding with each measurement, various third layer filter factors preferably are contained in measurement amount configuration (quantityConfig) In.

It is preferred that configured in the configuration of measurement amount comprising the first measurement amount relevant with EUTRA (quantityConfigEUTRA).The RSRP measurements based on CRS are preferably comprised in the first measurement amount configuration relevant with EUTRA Used filter factor (filterCoefficientRSRP) and based on CRS RSRQ measurement used in filter factor (filterCoefficientRSRQ).It should be noted that the filtering included in the first measurement amount configuration relevant with EUTRA Coefficient is preferably provided with default value (such as fc4).

The second measurement amount relevant with EUTRA can also be included in the configuration of measurement amount to configure (quantityConfigEUTRA-v12).It is preferred that included in the second measurement amount configuration relevant with EUTRA based on CSI-RS's Filter factor (filterCoefficientCSI-RSRP) used in RSRP measurements.

Further configured in the configuration of measurement amount comprising the threeth measurement amount relevant with EUTRA In the case of (quantityConfigEUTRA-v13 or quantityConfigEUTRA-U), can include has with EUTRA Close the first measurement amount configuration, the second measurement amount configuration beyond based on CRS RSRP measurement used in filter factor, be based on CRS RSRQ measurement used in filter factor, based on CSI-RS RSRP measurement used in filter factor, based on CSI-RS RSRQ measurements used in it is at least one in filter factor, filter factor used in rssi measurement.It should be noted that The default value of the filter factor included in the 3rd measurement amount configuration relevant with EUTRA is preferably arranged to " 0 (or fc0) ".

It should be noted that relevant with EUTRA the second measurement amount configuration and the 3rd measurement amount configure be alternatively and Additional configuration.It is institute for example, in the case of being notified of in terminal installation to base station apparatus with specific function (ability) The parameter of configuration.

It should be noted that it can be included in the 3rd measurement amount configuration relevant with EUTRA and the configuration pair of the 3rd measurement amount The identifier (quantityConfigId) answered.In the case where being configured with multiple 3rd measurement amount configurations, can be configured with more Individual identifier.With the 3rd corresponding identifier of measurement amount configuration can with the corresponding identifier (measId) of measurement configuration and Identifier (measObjectId), identifier corresponding with report configuration (reportConfigId) corresponding to measurement object configuration Associate.That is, it is possible to the measurement corresponding to corresponding measurement object configuring identifier and report configuration identifier As a result filter factor corresponding with the 3rd measurement amount configuring identifier is applied.It should be noted that measurement configuration, measurement object Configuration, report configuration are the configuration relevant with EUTRA respectively.

In addition, the threeth measurement amount configuration relevant with EUTRA may be embodied in measurement object configuration.That is, it is possible to The measurement result only configured to the measurement object in included carrier frequency configures included filter using the 3rd measurement amount Wave system number.

It should be noted that the situation in measurement object configuration is included in the 3rd measurement amount configuration relevant with EUTRA Under, can to detection cell and/or, the cell that is documented in neighbor cell list and/or, be documented in blacklist (black List the cell configuration filter factor in).For example, can both the common filtering system of list configuration be directed to the cell of list Number, can also be respectively configured filter factor to the cell of list.

In addition, in the case where the threeth measurement amount configuration relevant with EUTRA is included in measurement object configuration, can also By the information list relevant with filter factor.The information relevant with the filter factor after list can respectively with included in small Physical-layer cell identifier symbol in area's list, cell index associate.

If being configured in the configuration of measurement amount comprising the threeth measurement amount relevant with EUTRA, the configuration of the 3rd measurement amount is wrapped The filter factor contained can be only applied to the measurement result of the measurement object configuration for being configured with assigned frequency.For example, advising , can be only to the measurement pair comprising the assigned frequency in the case of determining frequency and being the frequency for belonging to unauthorized frequency range or LAA frequency ranges The measurement result of elephant applies the filter factor.It is excellent in measurement result corresponding with the measurement object in the frequency beyond assigned frequency Choosing does not configure included filter factor using the 3rd measurement amount.In this case, with the carrier frequency beyond assigned frequency Measurement object corresponding to preferably the application first measurement amount configuration relevant with EUTRA and/or the second measurement amount in measurement result The filter factor included in configuration.It should be noted that in the case of not configuring filter factor in the configuration of each measurement amount, terminal Device can be filtered based on the default value being separately configured in each frequency to measurement result application.

It should be noted that defined frequency is preferably frequency used in LAA cells.It is it should be noted that defined Frequency is preferably based on the frequency that LBT sends DS cell.It should be noted that defined frequency is preferably in unauthorized frequency range The frequency of the cell of middle utilization.It should be noted that defined frequency is preferably behaviour corresponding with the regulation index of operation frequency range Make the frequency of frequency range.It should be noted that defined frequency is preferably operation frequency range corresponding with the index of LAA operation frequency range Frequency.It should be noted that frequency as defined in above-mentioned is preferably to be indexed with the regulation of operation frequency range (E-UTRA operation frequency ranges) Corresponding operation frequency range.For example, operation frequency range manages preferably by form, to using form come each operation frequency range for managing to Go out corresponding index.The index is associated with corresponding uplink operation frequency range, downlink operation frequency range and dual-mode. It should be noted that uplink operation frequency range is operation frequency used in the reception of base station apparatus and the transmission of terminal installation Section, downlink operation frequency range is operation frequency range used in the transmission of base station apparatus and the reception of terminal installation.Need Bright, uplink operation frequency range and downlink operation frequency range are preferably (corresponding by lower frequency limit and upper limiting frequency respectively Frequency band) provide.It should be noted that dual-mode is preferably provided by TDD or FDD.It should be noted that LAA cells Dual-mode can also be by providing beyond TDD and FDD.Dashed forward for example, the dual-mode of LAA cells can also be described later sends Hair (comprises at least downlink burst, if comprising uplink burst be arbitrary).

For example, in the case where managing operation frequency range using form, to indexing, " 44 " are corresponding to operate frequency with index " 1 " Section is preferably to authorize frequency range (non-LAA frequency range), to " 255 " corresponding operation frequency range is indexed is preferably non-award with index " 252 " Weigh frequency range (LAA frequency range).It should be noted that in " 252 " are indexed, preferably do not apply on (n/a, not applicable) Line link operation frequency range, to downlink operation frequency range application 5150MHz-5250Hz, to dual-mode application FDD.In addition, Index in " 253 ", preferably preengage uplink operation frequency range (reservation uses for future), preengage downlink operation frequency range, it is right Dual-mode application FDD.In addition, in " 254 " are indexed, uplink operation frequency range (reservation uses for future) is preferably preengage, Downlink operation frequency range is preengage, to dual-mode application FDD.It should be noted that in " 255 " are indexed, preferably do not apply (n/a, not applicable) uplink operation frequency range is right to downlink operation frequency range application 5725MHz-5850Hz Dual-mode application FDD.It should be noted that 5150MHz-5250Hz and 5725MHz-5850Hz are preferably unauthorized frequency range (LAA frequency range).That is, above-mentioned defined frequency is preferably operation frequency range corresponding with index " 252 " extremely index " 255 ".

It should be noted that in the case where being provided for the combination of the frequency range of carrier aggregation by form, preferably only to being converged The measurement application of frequency in multiple operation frequency ranges of collection, corresponding to the index of operation frequency range corresponding with LAA frequency ranges and EUTRA The filter factor included in relevant the 3rd measurement amount configuration.

It should be noted that in the present embodiment, quantityConfigE-UTRA can be referred to as the first upper strata ginseng Number.It should be noted that quantityConfigE-UTRA can also be referred to as conventional (first) upper-layer parameters.Need to illustrate , quantityConfigE-UTRA-v12 can be referred to as the second upper-layer parameters.It should be noted that QuantityConfigE-UTRA-v12 can also be referred to as conventional (second) upper-layer parameters.It should be noted that by The filter factor that quantityConfigE-UTRA is specified can be referred to as the first filter factor.It should be noted that by The filter factor that quantityConfigE-UTRA is specified can also be referred to as conventional filter factor.It should be noted that by The filter factor that quantityConfigE-UTRA-v13 is specified can be referred to as the second filter factor.It should be noted that by The filter factor that quantityConfigE-UTRA-v13 is specified can also be referred to as new filter factor.

In other words, the measurement preferably in the frequency for authorizing frequency range (be used for RSRP and/or RSRQ and/or RSSI and/ Or CSI-RSRP and/or CSI-RSRQ and/or CSI-RSSI measurement) and frequency for unauthorized frequency range (LAA frequency ranges) Measurement (be used for RSRP and/or RSRQ and/or RSSI and/or CSI-RSRP and/or CSI-RSRQ and/or CSI-RSSI survey Amount) the different filter factor of middle use.That is for authorizing the filter factor of the measurement in the frequency of frequency range and being awarded for non- The filter factor of measurement in the frequency of power frequency range (LAA frequency ranges) is preferably independently configured by upper strata.

It should be noted that multiple filters for the measurement under a frequency (or frequency range) can be configured with terminal installation Wave system number, by the signaling from base station, which instruction (specified) applies to the measurement under each frequency (or the frequency range) Filter factor.Filtered for example, can be configured with terminal installation for first of the measurement under first frequency (or first frequency range) Coefficient and the second filter factor, by the signaling on upper strata, indicate to the measurement application under the first frequency (or first frequency range) Which of first filter factor or the second filter factor.It should be noted that can use physical layer signal (such as PDCCH/EPDCCH) indicate which filter factor used.

It should be noted that multiple filters for the measurement under a frequency (or frequency range) can be configured with terminal installation Wave system number, judge and (judge, selection) which is applied to the measurement under each frequency (or the frequency range) by terminal installation Filter factor.Filtered for example, can be configured with terminal installation for first of the measurement under first frequency (or first frequency range) Coefficient and the second filter factor, based on the information associated with indicating whether to have sent DS, indicate to the first frequency (or this first Frequency range) under measurement apply which of the first filter factor or the second filter factor.It should be noted that it is being based on and table Show that the information that whether have sent DS associations is determined as in the case of actually have sent DS, preferably using the first filter factor, in base In the case that the information associated with indicating whether to have sent DS is determined as that reality does not send DS, preferably it is using the second filtering Number.It should be noted that the information associated with indicating whether to have sent DS both can be the information clearly notified by base station apparatus, Can also be that terminal installation passes through the information by DS receiving power compared with defined threshold to obtain.

It should be noted that preferred pair multiple measurement objects corresponding with first frequency apply the first filter factor, pair with Multiple measurement objects corresponding to second frequency apply the second filter factor.In other words, the measurement that preferred pair associates with first frequency Corresponding multiple measurement objects apply the first filter factor, multiple measurements pair corresponding to pair measurement associated with second frequency As applying the second filter factor.For example, it is preferable to a pair multiple measurement objects corresponding with the frequency of a certain mandate frequency range apply first Filter factor, a pair multiple measurement objects corresponding with the frequency of a certain LAA frequency ranges apply the second filter factor.

In addition, in the case where the threeth measurement amount configuration relevant with EUTRA is included in DS measurement configurations, can be only right Measurement result based on corresponding DS applies the filter factor being included in the configuration of the 3rd measurement amount.

In addition, in the CSI-RS configurations that the threeth measurement amount configuration relevant with EUTRA is included in DS measurement configurations In the case of, the filtering system being included in the configuration of the 3rd measurement amount can be only applied to the measurement result based on corresponding CSI-RS Number.

For all measurements in addition to the measurement of the frequency association with LAA frequency ranges, terminal installation can be in order to comment Valency reporting criteria (Reporting standard) and use measurement result before, filtered using third layer.On the other hand, in order to With the measurement of the frequency association of LAA frequency ranges, terminal installation is preferably for appraisal report benchmark (Reporting standard) And before using measurement result, do not apply third layer to filter.

It should be noted that " do not apply third layer filter (filtering of Layer 3) " be preferably with for the measurement And the situation that third layer filter factor is configured to " 0 " is identical.For example, any one third layer is configured with terminal installation Filter factor, regardless of the configuration, the third layer filter factor for measurement is all configured to " 0 " by terminal installation.Need Illustrate, the output that " not applying third layer to filter " is preferably based only upon the most recent measurements from physical layer is using filter Output after ripple.It should be noted that " not applying third layer to filter " is preferably to be not based on old (before) filtered survey The output for measuring result is to apply filtered output.

In other words, terminal installation is preferably assumed to match somebody with somebody the third layer filter factor of the measurement for associating with assigned frequency It is set to " 0 ".For example, it is preferable to it is assumed that the filter factor of the measurement for being associated with LAA band frequencies is configured to by terminal installation “0”。

It should be noted that filter factor is preferably to be applicable only to the frequency in addition to regulation frequency range (assigned frequency) Section.In other words, preferably filtering is not applied to regulation frequency range.It should be noted that " not applying filtering " in present embodiment Including at least " it is assumed that k is arranged to " 0 " by terminal installation ".

In addition, in the case where the threeth measurement amount configuration relevant with EUTRA is included in report configuration, can be only right When being reported with the corresponding measurement result of this report configuration, using the filter factor included in the configuration of the 3rd measurement amount. In addition, in the case where the threeth measurement amount configuration relevant with EUTRA is included in report configuration, bar can also be triggered with event Part, which is mapped, to be configured.That is, it is possible to the filter in the configuration of the 3rd measurement amount is only included in specific event application Wave system number.

It should be noted that the configuration associated with measurement and/or report is preferably carried out by upper strata (higher layer).Change Yan Zhi, terminal installation is preferably based on to be configured with measuring and/or reporting the configuration associated from the signal on upper strata.In other words, with The parameter (information) of measurement and/or report association is preferably configured by the upper strata processing unit (upper strata disposal portion) of terminal installation.

Then, measurement (measurement) is illustrated.Base station apparatus uses RRC signaling (unlimited resources control letter Number) RRC connections reconfigure (RRC Connection Reconfiguration) message to terminal installation send measurement match somebody with somebody Put (Measurement configuration) message.Terminal installation included in measurement to configuring (Measurement Configuration) system information in message is configured, and is carried out according to the system information notified for service Cell (serving cell) and neighbor cell (include list cell (listed cell) and/or detection cell (detected cell)) measurement, event evaluation, measurement report.List cell is measurement object (Measurement Object the cell (cell notified from base station apparatus to terminal installation with neighbor cell list) listed in), detection cell are Detected in the frequency indicated by measurement object (Measurement object) by terminal installation but measurement object Unlisted cell is not (with detected by the terminal installation itself of neighbor cell list notice in (Measurement object) Cell).

Measurement (measurement) have three types (measurement (intra-frequency measurements) in frequency, Inter-frequency measurements (inter-frequency measurements) and inter-rat measurement (inter-RAT measurements)).Measurement (intra-frequency measurements) is the downlink in serving cell in frequency Measurement in frequency (down-link frequencies).Inter-frequency measurements (inter-frequency measurements) be with service Measurement in the different frequency of the down-link frequencies of cell.Inter-rat measurement (inter-RAT Measurements) be the wireless technology different from the wireless technology of serving cell (such as EUTRA) (such as UTRA, GERAN, CDMA2000 etc.) under measurement.

Measurement identifier (measId), measurement are included in measurement configuration (Measurement configuration) message Object (Measurement objects), report configuration (Reporting configurations) configuration addition and/or Modification and/or deletion, measurement amount configuration (quantityConfig), measurement interval configuration (measGapConfig), serving cell Quality threshold (s-Measure) etc..

Measurement interval configuration (measGapConfig) is used for measurement interval pattern (measurement gap Pattern configuration, activation (activation)/deactivation of measurement interval (measurement gap)) (deactivation) it is controlled.In measurement interval configures (measGapConfig), the situation as activation measurement interval Under information, reporting interval pattern (gap pattern), start system frame number (startSFN), start subframe number (startSubframeNumber).Which pattern is interval mode (gap pattern) regulation use as measurement interval (measurement gap).Start system frame number (startSFN) regulation and start measurement interval (measurement gap) System frame number (SFN：System Frame Number).Start subframe number (startSubframeNumber) regulation to start The subframe number of measurement interval (measurement gap).

Measurement interval refers to, in the case where uplink/downlink sends and is not scheduled, is possibly used for terminal dress Put (time, subframe) during measuring.

Serving cell quality threshold value (s-Measure) represents the threshold relevant with the quality of serving cell (serving cell) Value, for controlling whether to need terminal installation to measure (measurement).Serving cell quality threshold value (s-Measure) It is configured to the value for RSRP.

Here, measurement identifier (measId) is used to make measurement object (Measurement objects) and report configuration (Reporting configurations) is linked, and specifically, makes measurement object identifier (measObjectId) and report Configuring identifier (reportConfigId) links.In measurement identifier (measId), a measurement object identifier (measObjectId) it is corresponding with a report configuration identifier (reportConfigId).Measurement configuration (Measurement Configuration) message can match somebody with somebody to measurement identifier (measId), measurement object (Measurement objects), report The relation for putting (Reporting configurations) is added, changed and deleted.

MeasIdToRemoveList is by the instruction of specified measurement identifier (measId) deletion.Now, with institute The measurement identifier (measId) specified corresponding measurement object identifier (measObjectId) and report configuration identifier (reportConfigId) it is not deleted and is maintained.The instruction can specify multiple measurement identifiers (measId) simultaneously.

MeasIdToAddModifyList is so that specified measurement identifier (measId) and specified measurement pair The mode being mapped as identifier (measObjectId) and specified report configuration identifier (reportConfigId) Modify；Or make specified measurement object identifier (measObjectId) and specified report configuration identifier (reportConfigId) it is mapped with specified measurement identifier (measId), and additional specified measurement identifier (measId) instruction.The instruction can specify multiple measurement identifiers (measId) simultaneously.

Measurement object (Measurement objects) is according to wireless access technology (RAT：Radio Access Technology) and frequency provides.It is directed in addition, report configuration (Reporting configurations) is present EUTRA regulation and the regulation for the RAT beyond EUTRA.

Measurement object (Measurement objects) includes corresponding with measurement object identifier (measObjectId) Measurement object EUTRA (measObjectEUTRA) etc..

It should be noted that in the case of carrying out the configuration of multiple measurement objects in a frequency, for a frequency It is configured with multiple measurement objects (Measurement objects).In other words, multiple measurement objects are carried out in a frequency In the case of configuration, multiple measurement objects (Measurement objects) corresponding with a frequency are configured with.In a frequency In the case of the configuration that multiple measurement objects are carried out in rate, multiple surveys are configured with for multiple measurements corresponding with a frequency Measure object (Measurement objects).In other words, can multiple measurement objects be configured with common frequency.In other words, Multiple measurement objects can also be configured with identical EUTRA carrier wave frequency informations (eutra-CarrierInfo or carrierFreq)。

Measurement object identifier (measObjectId) is to be used to match somebody with somebody measurement object (Measurement objects) Put the identifier being identified.As described above, the configuration of measurement object (Measurement objects) is according to wireless access skill Art (RAT) and frequency provide.Measurement object (Measurement objects) for EUTRA, UTRA, GERAN, CDMA2000 and separately standardize.Measurement object (Measurement objects), i.e. measurement object EUTRA for EUTRA (measObjectEUTRA) information that regulation is applied to EUTRA neighbor cell.In addition, measurement object EUTRA (measObjectEUTRA) the measurement object EUTRA of different frequency is by as different measurement object (Measurement in Objects) handle, otherwise allocated has measurement object identifier (measObjectId).

One example of the information of measurement object is illustrated.

Hereinafter, the details of LAA cells are illustrated.

Frequency used in LAA cells is shared with other communication systems and/or other LTE operators.In the shared of frequency In, the fairness of LAA cells and other communication systems and/or other LTE operators is required.For example, made in LAA cells , it is necessary to fair frequency sharing technology (method) in communication mode.In other words, LAA cells are to carry out that (use) can be applied The communication mode (communication process) of fair frequency sharing technology.

One example of fair frequency sharing technology is LBT (Listen-Before-Talk：Listem-before-talk).LBT exists A certain base station or terminal before sending signal, (are done using a certain frequency (component carrier, cell) to the jamming power of the frequency Disturb signal, receiving power, reception signal, noise power, noise signal) etc. measure (detection), be empty to the frequency thus Not busy state (blank state, congestion state, Presence, Occupied) or busy condition (non-blank state, non-congested shape State, Absence, Clear) it is identified and (detection, assumes, determines).The feelings that the frequency is idle condition are being identified as based on LBT Under condition, the regulation timing that the LAA cells can be on that frequency sends signal.It is busy condition being identified as the frequency based on LBT In the case of, the regulation timing of the LAA cells on that frequency does not send signal.It can be controlled as follows by LBT： Signal transmitted by other base stations comprising other communication systems and/or other LTE operators and/or terminal is not done Disturb.

LBT process is defined as before a certain base station or terminal are using its frequency (channel) using the mechanism of CCA verifications. In order to identify that the frequency is idle condition or busy condition, the CCA carries out whetheing there is other signals for decision in the channel Power detection or signal detection.It should be noted that in the present embodiment, CCA definition can also be with LBT definition phase Together.

In CCA, the method for determining to whether there is other signals can use various methods.For example, CCA is based in a certain frequency Jamming power whether determined more than a certain threshold value.In addition, for example, CCA based on the defined signal in a certain frequency or Whether the receiving power of channel is determined more than a certain threshold value.The threshold value can be with prespecified.The threshold value can by base station or Other terminal configurations.The threshold value can at least be based on other values (parameter) such as transmit power (maximum transmit power) and be determined (configuration).

It should be noted that the CCA in LAA cells by connecting (configuration) in the terminal of the LAA cells without being identified.

LAA cells can be defined as the cell different from the secondary cell using dividing frequency.For example, LAA cells by with It is set to different from the configuration of the secondary cell using dividing frequency.The part for being configured at the parameter of LAA cells is not configured in and made With the secondary cell of dividing frequency.The part for being configured at the parameter of the secondary cell using dividing frequency is not configured in LAA cells. In the present embodiment, LAA cells are set to the cell different from main plot and secondary cell to illustrate, but can also will LAA cell definitions are one of secondary cell.In addition, conventional secondary cell is also referred to as the first secondary cell, LAA cells are also referred to as Two secondary cells.In addition, conventional main plot and secondary cell is also referred to as first service cell, LAA cells are also referred to as the second clothes Business cell.

In addition, LAA cells can also be different from conventional frame structure type.For example, conventional serving cell uses (configuration ) the first frame structure type (FDD, frame structure type 1) or the second frame structure type (TDD, frame Structure type 2), but LAA cells use (being configured with) the 3rd frame structure type (frame structure type 3)。

Here, non-dividing frequency is the frequencies different from distributing to the dividing frequency of regulation operator as proprietary frequency. For example, non-dividing frequency is frequency used in WLAN.In addition, for example, non-dividing frequency is not matched somebody with somebody in conventional LTE The frequency put, dividing frequency are the frequencies that can be configured in conventional LTE.In the present embodiment, LAA cells will be configured at Frequency is set to non-dividing frequency and illustrated, but is not limited to this.That is, non-dividing frequency can be with being configured at LAA cells Frequency is replaced.For example, non-dividing frequency is can not to be configured at the frequency of main plot, it is the frequency that can only be configured at secondary cell.Example Such as, non-dividing frequency also includes the frequency shared to multiple operators.In addition, for example, non-dividing frequency is only to be configured at progress The cell of configuration, hypothesis and/or the processing different from conventional main plot or secondary cell.

LAA cells can be set to structure and communication using radio frames, physical signalling and/or the physical channel in LTE etc. The cell of the mode different from conventional mode in terms of process.

For example, in LAA cells, (transmission) is not configured the defined of (transmission) is configured in main plot and/or secondary cell Signal and/or channel.The defined signal and/or channel include CRS, DS, PDCCH, EPDCCH, PDSCH, PSS, SSS, PBCH, PHICH, PCFICH, CSI-RS and/or SIB etc..For example, the signal and/or channel that are not configured in LAA cells are as follows. It should be noted that signal described below and/or channel can also be applied in combination.It should be noted that in present embodiment In, the signal and/or channel that are not configured in LAA cells can be interpreted the undesirable letter sent from the LAA cells of terminal Number and/or channel.

(1) in LAA cells, the control information of physical layer is not sent by PDCCH, and is only sent by EPDCCH.

(2) in LAA cells, even in activation (opening) subframe in, also not by all subframes come send CRS, DMRS, URS, PDCCH, EPDCCH and/or PDSCH, terminal does not assume that to be transmitted by all subframes.

(3) in LAA cells, terminal assumes to send DRS, PSS and/or SSS in the subframe of activation (opening).

(4) in LAA cells, the relevant information of the mapping with CRS is notified, to each subframe, based on the information to enter by terminal The hypothesis of row CRS mapping.For example, the hypothesis of CRS mapping is not mapped to all resource elements of the subframe.CRS mapping Hypothesis be not mapped to the subframe a part of resource element (for example, beginning 2 OFDM symbols in all resource elements). The hypothesis of CRS mapping is mapped to all resource elements of the subframe.In addition, for example, the information relevant with CRS mapping is by this LAA cells or the cell different from LAA cells notice.The information relevant with CRS mapping is included in DCI, passes through PDCCH Or EPDCCH is notified.

In addition, for example, in LAA cells, configuration (transmission) does not configure the rule of (transmission) in main plot and/or secondary cell Fixed signal and/or channel.

In addition, for example, in LAA cells, downlink component carrier or subframe are only defined, only sends down link signal And/or channel.That is, in LAA cells, undefined uplink component carrier or subframe, do not send uplink signal and/or Channel.

In addition, for example, in LAA cells, can corresponding to DCI (Downlink Control Information：It is descending Link control message) form is different from the DCI format that can correspond to main plot and/or secondary cell.Define and correspond only to LAA The DCI format of cell.Included corresponding to the DCI format of LAA cells only to the effective control information of LAA cells.

In addition, for example, in LAA cells, the hypothesis of signal and/or channel is different from conventional secondary cell.

First, the hypothesis to signal and/or channel in conventional secondary cell illustrates.Meet one of following condition Point or whole terminals be assumed in addition to DS transmission, PSS, SSS, PBCH, CRS, PCFICH, PDSCH, PDCCH, EPDCCH, PHICH, DMRS and/or CSI-RS may not sent by the secondary cell.Lead to all the time in addition, the terminal is assumed to DS Cross secondary cell transmission.In addition, the hypothesis, which continues to, receives activation life in secondary cell of the terminal in a certain carrier frequency The subframe for making and (being used for the order activated).

(1) the terminal-pair configuration relevant with DS (parameter) is supported.

(2) terminal is configured with the RRM measurements based on DS in the secondary cell.

(3) secondary cell is deactivation (state being deactivated).

(4) terminal is not configured with receiving MBMS by upper strata in the secondary cell.

In addition, in the case where the secondary cell is activation (state being activated), terminal is assumed in the regulation configured Subframe or all subframes in, PSS, SSS, PBCH, CRS, PCFICH, PDSCH, PDCCH, EPDCCH, PHICH, DMRS And/or CSI-RS is sent by the secondary cell.

Then, an example of the hypothesis to signal and/or channel in LAA cells illustrates.Meet following condition Some or all of terminal be assumed to comprising in being sent in of DS, PSS, SSS, PBCH, CRS, PCFICH, PDSCH, PDCCH, EPDCCH, PHICH, DMRS and/or CSI-RS may not sent by the LAA cells.In addition, the hypothesis continues to this Terminal receives the subframe of activation command (being used for the order activated) in the secondary cell in a certain carrier frequency.

(1) the terminal-pair configuration relevant with DS (parameter) is supported.

(2) terminal is configured with the RRM measurements based on DS in the LAA cells.

(3) the LAA cells are deactivation (state being deactivated).

(4) terminal is not configured with receiving MBMS by upper strata in the LAA cells.

In addition, another example of the hypothesis to signal and/or channel in LAA cells illustrates.In the LAA cells In the case of deactivating (state being deactivated), hypothesis and auxiliary small of signal and/or channel in the LAA cells in the past The hypothesis of signal and/or channel in area is identical.In the case where the LAA cells is activation (state being activated), the LAA is small The hypothesis of signal and/or channel in area is different from the hypothesis of signal and/or channel in conventional secondary cell.For example, at this In the case that LAA cells is activation (state being activated), terminal is assumed to the defined son except being configured in the LAA cells Beyond frame, PSS, SSS, PBCH, CRS, PCFICH, PDSCH, PDCCH, EPDCCH, PHICH, DMRS and/or CSI-RS may be not Sent by the LAA cells.Its details will be explained below.

Then, an example of the communication process in LAA cells is illustrated.In LAA cells, it can be existed based on LBT Timing independent of the border (Subframe boundary) of subframe starts the transmission of channel and/or signal.In addition, in LAA , can be based on LBT and the Maximum Burst Size that can be sent on the border (Subframe boundary) independent of subframe in cell Timing terminate the transmission of channel and/or signal.That is, channel and/or signal can be sent by part subframe.Part subframe example It can such as be defined as below.Here, in the present embodiment, the OFDM symbol that can be sent represented by the subframe of part can be defined as Terminal assumes to send each or all channel and/or signal.

(1) in a certain subframe, can send from the OFDM symbol of the midway of the subframe to the last OFDM symbols of the subframe The region on number (border of subframe).In the present embodiment, also referred to as Part I subframe.

(2) in a certain subframe, can send from the initial OFDM symbol (border of subframe) of the subframe to the subframe The region of the OFDM symbol of midway.In the present embodiment, also referred to as Part II subframe.

(3) in a certain subframe, the OFDM symbols of the midway from the OFDM symbol of the midway of the subframe to the subframe can be sent Number region.In the present embodiment, also referred to as Part III subframe.

In addition, in the subframe of part, the OFDM symbol of the midway of subframe can be limited to specified quantity.For example, the stated number Measure as 2,3 and/or 4.

In addition, in the case where the specified quantity is 2, such as a time slot or a subframe (2 time slots) can be set to In any one.That is, the unit of the 2nd EPDCCH time orientation is a time slot or a subframe.The 2nd EPDCCH when Between direction unit for time slot in the case of, also may be used by the unit of the PDSCH of the 2nd EPDCCH scheduling time orientation To be set to a time slot.In other words, in the same manner as conventional LTE by units of a subframe communication means (in a manner of) and with A time slot as conventional LTE half is switched use for the communication means of unit.By in units of a time slot, The delay in radio communication can be cut down.Thus, in addition to the communication means same with conventional LTE, additionally it is possible to further real Communication means, the communication means for now cutting down the delay in radio communication are possibly realized.This can not only be applied to LAA cells, also It can be suitably used for the LTE used in conventional distribution frequency band.That is, all methods, the structure illustrated in present embodiment can not only fit For LAA cells, moreover it is possible to the LTE used suitable for conventional distribution frequency band.

Here, in LAA cells, the LAA cells in the case where that can send channel and/or signal are defined based on LBT During being transmitted.Maximum Burst Size is also referred to as during this period, and the channel and/or signal sent in this period is also claimed For burst.For example, Maximum Burst Size is 4 milliseconds (4 subframe lengths).Therefore, in each burst, the son of the beginning of burst Frame is Part I subframe, and the last subframe of burst is Part II subframe.It should be noted that part subframe is also referred to as Floating subframe.In addition, part subframe can also send (nothing comprising the channel and/or signal for not supplying to illustrate in present embodiment Method is sent) symbol/subframe subframe.

In addition, in a certain subframe, can send from the initial OFDM symbol (border of subframe) of the subframe to the subframe The subframe in region of last OFDM symbol (border of subframe) be also referred to as whole subframes.Whole subframes be part subframe with Outer subframe.Whole subframes are the subframes in each burst, beyond the subframe of beginning or the last subframe of burst of burst. Whole subframes can also be the symbol for not including the channel for not supplying to illustrate in present embodiment and/or signal transmission (can not be sent) Number/subframe of subframe.In addition, the subframe in LAA cells can also be with the conventional subframe identical structure in conventional cell and/ Or carry out the subframe of same treatment.

Then, an example of the communication process in LAA cells is illustrated.In LAA cells, provided based on LBT During the LAA cells can be transmitted in the case of sending channel and/or signal.It is also referred to as during this period maximum prominent Length is sent out, the channel and/or signal sent within this period also referred to as happens suddenly.Burst is by more than one continuous downlink Subframe is formed.And then in a burst in the presence of more than one continuous uplink sub-frames in the case of, preferably more than one connect The structure that followed by more than one continuous uplink sub-frames of continuous downlink subframe.It should be noted that it is preferred that Exist between more than one continuous downlink subframe and more than one continuous uplink sub-frames and be used to switch descending chain Road and the subframe of up-link.

In addition, in order to illustrate, it is prominent that more than one continuous downlink subframe in burst is referred to as downlink transmission Hair, more than one continuous uplink sub-frames in burst are referred to as up-link and send burst, will be used to switch uplink The subframe of road and downlink is referred to as special subframe (special subframe in LAA cells).

It should be noted that the special subframe in LAA cells is to include DwPTS (Downlink Pilot Time Slot： Descending pilot frequency time slot), GP (Guard Period：Guard period) and UpPTS (Uplink Pilot Time Slot：It is up Pilot time slot) at least one subframe in these three fields.The configuration relevant with the special subframe in LAA cells can pass through The signaling of RRC signaling, PDCCH or EPDCCH is configured or notified.The configuration pin to DwPTS, GP and UpPTS at least one Individual setup time length.In addition, the configuration is the index information for the candidate for representing prespecified time span.In addition, this is matched somebody with somebody Put can use be configured in conventional TDD cell special subframe configuration used in DwPTS, GP and UpPTS identical Time span.In addition, the configuration can use be configured in conventional TDD cell special subframe configuration used in DwPTS, Time spans different GP and UpPTS.That is, the time span that can be sent in a certain subframe is based on DwPTS, GP and UpPTS Any one and determine.

Furthermore it is preferred that in the GP of special subframe in LAA cells, terminal carries out LBT or CCA.That is, terminal based on LBT identifications (detection, assume, determine) are that to send the frequency of burst for up-link be that busy condition (non-blank state, non-is gathered around Plug-like state, Absence, Clear) in the case of, stop (without, cancel, abandon) up-link sends the transmission of burst. That is, terminal is identifying and (detection, assumed, decision) that to send the frequency of burst for up-link be that idle condition is (empty based on LBT Configuration state, congestion state, Presence, Occupied) in the case of, carry out the transmission that the up-link sends burst.

In other words, burst there is a situation where to be sent by downlink to happen suddenly to form and sent by downlink and happen suddenly, be special Subframe and up-link send the situation that burst is formed.It should be noted that it can also forbid in a burst in the absence of descending Link sends burst and only exists the structure that up-link sends burst.It should be noted that descending chain is not present in a burst Road send burst and only exist up-link send burst in the case of, burst can only by up-link send burst form (i.e., it is possible to special subframe is not present).

In addition, the downlink transmission burst and M that are made up of in burst N number of continuous downlink subframe are individual continuous Uplink sub-frames form up-link send burst form in the case of, preferably to terminal notification N and M.It can also remove Beyond N and M, configuration to terminal notification special subframe.

Fig. 5 is the figure for an example for representing the communication process in a certain LAA cells.Fig. 5 is shown shown in subframe #0~9 10 subframes and symbol #0~13 in subframe #3 14 symbols (OFDM symbol).In addition, in an example, LAA Cell maximum can send the signal of 4 milliseconds (equivalent to 4 subframes), and CCA is carried out by the symbol #5 in subframe #3.It is in addition, false Determine LAA cells and identify that its frequency is idle condition in the CCA, and the situation of signal can be sent from symbol immediately after. In Fig. 5, signal is sent to the regulation symbol in subframe #6 by LAA cells from the symbol #6 in subframe #3.

In Figure 5, symbol or son shown in symbol/subframe of channel and/or signal transmission (can not be sent) are not being supplied In frame, the LAA represents that what does not send.In addition, in Figure 5, the symbol of (can be sent) is being sent for channel and/or signal Number/subframe shown in symbol or subframe in, the LAA represent at least send PDSCH and with PDSCH establish associate terminal spy There is reference signal.In addition, PDSCH, which in units of resource block pair, is mapped (scheduling), arrives each terminal.Have with the mapping (scheduling) The information of pass is notified by the PDCCH that is sent by each subframe or EPDCCH.The mapping for PDSCH in a certain subframe is believed Breath can both be notified by identical subframe, can also be notified by another subframe.

In Figure 5, in the case of sending PDSCH in symbol #6~13 during LAA cells use subframe #3, receiving should PDSCH terminal needs to identify symbol #6~13 that the PDSCH is mapped in subframe #3.

In an example of the method that this is identified, in the defined subframe (such as subframe #3) of the LAA cells, Use the information for identifying the symbol sent for channel and/or signal.For example, the information be it is following any or by it Combine after information.

(1) information is in the defined subframe, represents to supply the letter of the primary sign of channel and/or the symbol of signal transmission Breath.The information for representing primary sign is any one in 0 to 13, and each value represents the symbol number as primary sign.

(2) information is in the defined subframe, represents to supply the letter of the primary sign of channel and/or the symbol of signal transmission Breath.The information for representing primary sign be 0 to 13 value in prespecified value be indexed after index information.

(3) information is in the defined subframe, represents to supply the information of the bitmap of channel and/or the symbol of signal transmission. The information of bitmap is formed by 14.In the information of bitmap, in the case that each position is a kind of state (such as 1), represent for letter The symbol that road and/or signal are sent, in the case that each position is another state (such as 0), expression does not supply channel and/or signal The symbol of transmission.

(5) the last symbol of symbol that the information is in the defined subframe, represents not supply channel and/or signal to send Information or represent the symbol for not supplying channel and/or signal to send symbol quantity information.For example, the last symbol It is any one in 0 to 13, each value represents the symbol number as the last symbol.For example, represent the symbol quantity Information is any one in 1 to 14, and each value represents the symbol quantity.

(6) the last symbol of symbol that the information is in the defined subframe, represents not supply channel and/or signal to send Information or represent the symbol for not supplying channel and/or signal to send symbol quantity information.For example, the last symbol Be 0 to 13 value in prespecified value be indexed after index information.For example, the information for representing the symbol quantity be 1 to Index information after prespecified value is indexed in 14 value.

In addition, for identify for channel and/or signal transmission symbol information Notification Method for example using it is following this The method of sample.

(1) Information Pull by RRC signaling or MAC signaling to the parameters of the LAA cell configurations (notice) come Notice.In the case where a certain serving cell is LAA cells, in a certain subframe, the symbol configured does not supply channel and/or letter Number send, other symbols are sent for channel and/or signal.For example, the symbol that channel and/or signal are sent is not supplied in a certain subframe In be configured as symbol #0 and 1.The symbol for not supplying channel and/or signal to send be configured as in a certain subframe symbol #2~ 13.In addition, the configuration can also according to channel and/or signal difference (can be independently).For example, in a certain subframe, terminal It is configured as EPDCCH and is mapped to symbol #2~13, and is configured as PDSCH and is mapped to symbol #1~13.It is in addition, for example, right The scope (desirable value) of the PDSCH of LAA cell configurations primary sign can be with the PDSCH's to conventional secondary cell configuration The scope (1~4) of primary sign is different.To the scope of the PDSCH and/or EPDCCH of LAA cell configurations primary sign for 0~ 13。

(2) (assisted cell, master are small from the LAA cells or the serving cell different from the LAA cells for the Information Pull Area or secondary cell) PDCCH that sends or EPDCCH notify.Included by the DCI of PDCCH or EPDCCH carryings (transmission) The information.

(3) Information Pull notifies for notifying channel or the signal of the information.For notify the information channel or Signal is only sent to LAA cells.For notify the information channel or signal by the LAA cells or with the LAA cells not Same serving cell (assisted cell, main plot or secondary cell) is sent.

(4) candidate of the information by RRC signaling or MAC signaling to the LAA cell configurations (notice).Based on logical The information that the DCI of PDCCH or EPDCCH carryings (transmission) is included is crossed, is selected from the candidate of the information.For example, pass through RRC signaling or MAC signal deployment have the information for representing 4 primary signs, represent the Information Pull of 2 of one of them PDCCH or EPDCCH signaling notifies.

(5) channel for the defined resource element that the Information Pull is mapped in a certain subframe or signal notify.For example, The defined resource element is multiple resource elements in defined symbol.For example, defined symbol is last in the subframe Symbol.For for notifying that subframe that the channel of the information or signal map both can be all subframes in LAA cells, also may be used To be the subframe of prespecified subframe or signal deployment by RRC.

(6) information is predefined.In the case where a certain serving cell is LAA cells, in a certain subframe, it is specified that Symbol do not supply channel and/or signal to send, other symbols are sent for channel and/or signal.For example, channel and/or letter are not supplied Number send symbol be symbol #0 and 1 in a certain subframe.The symbol for not supplying channel and/or signal to send is in a certain subframe Symbol #2~13.In addition, the regulation can also according to channel and/or signal difference (can be independently).For example, in a certain subframe In, terminal is assumed to EPDCCH and is mapped to symbol #2~13, and is assumed to PDSCH and is mapped to symbol #1~13.

In another example for the method that this is identified, in the defined subframe (such as subframe #3) of the LAA cells In, the symbol that terminal-pair is sent for channel and/or signal is detected.In addition, it can also be configured with terminal for being somebody's turn to do The auxiliary information of detection.For example, the detection method uses following such method.

(1) detection is carried out based on the defined signal in the defined subframe is mapped to.Terminal is based in the regulation Subframe in whether detect the signal of prespecified signal or configuration to detect the symbol for channel and/or signal transmission. In the case that terminal detects the signal of prespecified signal or configuration in a certain symbol of the defined subframe, this is advised The Symbol recognition after a certain symbol in fixed subframe is the symbol sent for channel and/or signal.It is for example, prespecified Signal or the signal of configuration be CRS, DMRS and/or URS.

(2) detection is carried out based on the defined channel in the defined subframe is mapped to.Terminal is based in the regulation Subframe in whether detect the channel of prespecified channel or configuration to detect the symbol for channel and/or signal transmission. In the case that terminal detects the channel of prespecified channel or configuration in a certain symbol of the defined subframe, this is advised The Symbol recognition after a certain symbol in fixed subframe is the symbol sent for channel and/or signal.It is for example, prespecified Channel or the channel of configuration be EPDCCH.Specifically, terminal be assumed to a certain symbol in the defined subframe it EPDCCH is mapped with symbol afterwards, to carry out EPDCCH monitoring (detection process, blind Detecting).Here, terminal can be to vacation It is set to the primary sign progress blind Detecting for being mapped with EPDCCH.Furthermore, it is assumed that to be mapped with EPDCCH primary sign or starting The candidate of symbol be able to can also be both configured with predefined.

In addition, in Fig. 5 subframe #3, PDCCH, EPDCCH and/or PDSCH can be with to the mapping method of resource element Mapping method in other subframes is different.For example, the mapping method can use following method.It is it should be noted that following Mapping method (mapping order) other signals such as reference signal, synchronizing signal can also be applied to.

(1) in the mapping method, PDCCH, EPDCCH and/or PDSCH are mapped from the last symbol in the subframe. That is, the mapping of PDCCH, EPDCCH and/or PDSCH to resource element (k, l) is distributed Physical Resource Block, can reflected It is that maximum OFDM numberings (i.e., the last symbol in time slot) are carried out successively from OFDM symbol numbering l in the resource element penetrated Mapping.In addition, mapped successively from the last time slot (the 2nd time slot) of subframe.In addition, in each OFDM symbol, this A little channels are that minimum subcarrier is mapped successively from subcarrier number k.

(2) in the mapping method, PDCCH, EPDCCH and/or PDSCH skip the symbol for not supplying channel and/or signal to send Number, and be mapped to for the resource element in channel and/or the symbol of signal transmission.That is, in PDCCH, EPDCCH and/or PDSCH Mapping in, do not supply the resource element for the symbol that channel and/or signal send by carry out rate-matched.

(3) in the mapping method, PDCCH, EPDCCH and/or PDSCH are not skipped and are not supplied what channel and/or signal were sent Symbol, and be mapped to for the resource element in channel and/or the symbol of signal transmission.In other words, PDCCH, EPDCCH and/or PDSCH applies to the symbol sent for channel and/or signal and the symbol for not supplying channel and/or signal to send without difference Mapping, but be not transmitted to the channel for being mapped to the symbol for not supplying channel and/or signal to send, to be mapped to supply channel and/ Or the channel of the symbol of signal transmission is transmitted.That is, in PDCCH, EPDCCH and/or PDSCH mapping, channel is not supplied And/or the resource element of the symbol of signal transmission is punctured.

Fig. 6 is the figure for an example for representing the communication process in a certain LAA cells.Hereinafter, pair with it is illustrated in fig. 5 interior The difference of appearance illustrates.In an example, CCA is carried out by the symbol #5 in subframe #3.Furthermore, it is assumed that LAA is small Area identifies that its frequency is idle condition in the CCA, and the situation of signal can be sent from symbol immediately after.LAA cells will Signal is sent to the defined symbol in subframe #6 from the symbol #5 in subframe #3.

In a Fig. 6 example, the symbol #6 and 7 in subframe #3 is the symbol sent for reservation signal.Reservation letter Number (that is, accorded with to the symbol and then sent for channel and/or signal after CCA symbol (that is, symbol #5) is and then carried out Number #6) before sent.Effect caused by the reservation signal is as follows.As illustrated in fig. 5, even in being pre-provisioned with or In the case of the candidate for being configured with the symbol sent for channel and/or signal, LAA cells also can neatly carry out CCA, and disobey The quantity of the Lai Yu candidates.

Even the terminal received to the channel and/or signal that are sent from the LAA cells, reservation signal are not also connect Receive (identification).That is, in the case where channel and/or signal can not be sent after carrying out CCA, in order that the LAA for carrying out the CCA is small Area ensures (reservation) frequency and sends reservation signal.

The symbol sent for reservation signal can be mapped with the channel sent with the symbol by being sent for channel and/or signal And/or the channel and/or signal that signal is different.That is, the channel and/or signal quilt being mapped on the symbol sent for reservation signal Terminal recognition (reception).For example, terminal is identified based on the channel and/or signal that are mapped on the symbol sent for reservation signal The symbol sent for channel and/or signal.In addition, for example, terminal uses the letter being mapped on the symbol for reservation signal transmission Road and/or signal come and the LAA cell synchronous (with fixed).

In addition, the reservation signal in present embodiment is also referred to as initial signal.Initial signal is the beginning hair in burst The signal sent, it can be distinguished with PDSCH, EPDCCH, PDCCH in the burst and/or reference signal.In addition, initial signal Can include the control information relevant with the burst, the control information relevant with the channel in the burst and/or signal or with Sending the relevant control information of the cell of the burst.

Fig. 7 is the figure for an example for representing the communication process in a certain LAA cells.Hereinafter, pair with it is illustrated in fig. 5 interior The difference of appearance illustrates.It is same with a Fig. 5 example in an example, entered by the symbol #5 in subframe #3 Row CCA.Furthermore, it is assumed that LAA cells identify that its frequency is idle condition in the CCA, and can be sent from symbol immediately after The situation of signal.In the figure 7, the symbol in the subframe #7 that signal is sent to after 4 milliseconds by LAA cells from the symbol #6 in subframe #3 Number #5.

In a Fig. 7 example, LAA cells are in the subframe comprising the symbol for carrying out CCA, by reservation signal from immediately The symbol after the symbol for carrying out CCA and send symbol to the end.In addition, son of the LAA cells from the symbol for including progress CCA Next subframe of frame sends channel and/or signal.In addition, the reservation signal in Fig. 7 includes reservation signal illustrated in fig. 6.

For example, in the figure 7, terminal can be assumed to be sent by the subframe after subframe #4 for channel and/or signal.By This, terminal is assumed to send for channel and/or signal from the initial symbol of subframe.Therefore, the base station comprising LAA cells is right Its terminal sends channel and/or signal and the aspect for notifying the control information for the channel and/or signal, using with Toward same method.

In addition, in the figure 7, channel and/or signal can be sent to symbol by LAA cells in subframe #7 from initial symbol Number #5.For example, LAA cells can be to the defined symbol that terminal transmission is mapped in subframe #7 to symbol #5 resource PDSCH and/or EPDCCH.Accorded with addition, LAA cells can send the initial symbol being mapped in subframe #7 to terminal as defined in Number resource on PDCCH.For example, defined symbol is the information sent by PCFICH, based on the OFDM for sending PDCCH The related information of the quantity of symbol and determine.In addition, for example, defined symbol is by the control information of RRC signal deployment, base In the letter for the OFDM primary signs for representing to be used for the PDSCH by EPDCCH, PDCCH scheduling and the PDSCH by EPDCCH scheduling Cease and determine.

In addition, in the figure 7, LAA cells can notify the last symbol sent for channel and/or signal in subframe #7 Or it is allocated to terminal.In a certain subframe of LAA cells, for making the information and its information of terminal recognition its last symbol Notification Method can use the method illustrated in a Fig. 5 example.The method illustrated in a Fig. 5 example is to be used to know The information of symbol sent for channel and/or signal and its Notification Method of information in other Fig. 5.For example, LAA cells will be with it The relevant information of last symbol is included in the DCI by subframe the #7 PDCCH sent or EPDCCH notice.Thus, LAA cells , can be efficiently in the case of the symbol for the midway that channel and/or signal can be sent to subframe the subframe #7 in as Fig. 7 Use resource.In addition, for example, the information relevant with its last symbol is included in signaling or MAC by RRC by LAA cells In the information of signal deployment.

In addition, in the figure 7, the method to the sending method in the sending method in subframe #3 and subframe #7 is applied in combination It is illustrated, but is not limited to this.Can also separately it use in the sending method and subframe #7 in subframe #3 Sending method.In addition it is also possible to part or all by Fig. 5~method illustrated in fig. 7 is respectively combined use.

In addition, in Fig. 7 subframe #7, the mapping of PDCCH, EPDCCH and/or PDSCH to resource element can also be with it Mapping in its subframe is different.

In addition, in LAA cells, the subframe of channel and/or signal can be sent to all OFDM symbols in a subframe (i.e. subframe #4~6 in Fig. 5~Fig. 7) can also be as with sending channel without a part of OFDM symbol in one subframe of normal direction And/or subframe (that is, the subframe #7 in subframe #3 and Fig. 7 in Fig. 5~Fig. 7) different subframe of signal is identified, matched somebody with somebody Put or notify.For example, the subframe of channel and/or signal and conventional service can be sent to all OFDM symbols in a subframe Subframe in cell is equal.

In the present embodiment, all OFDM symbols in no one subframe of normal direction send the subframe of channel and/or signal Also referred to as the first LAA subframes.The subframe of channel and/or signal is sent without a part of OFDM symbol in one subframe of normal direction It is referred to as the 2nd LAA subframes.The subframe that channel and/or signal can be sent to all OFDM symbols in a subframe is also referred to as 3rd LAA subframes.In addition, the 2nd LAA subframes are also referred to as part subframe, the 3rd LAA subframes are also referred to as whole subframes.Need Illustrate, the 2nd LAA subframes include Part I subframe, Part II subframe and/or Part III subframe.

In addition, for using the method for the LAA subframes of terminal recognition the first, the 2nd LAA subframes and the 3rd LAA subframes The method illustrated in present embodiment.For example, it is used to identify for channel and/or signal transmission for identifying that their method uses Symbol information and its Notification Method.

In addition, for making the method for the LAA subframes of terminal recognition the first, the 2nd LAA subframes and the 3rd LAA subframes can also be by PDCCH or RRC signaling is clearly notified or configured.

In addition, for making the method for the LAA subframes of terminal recognition the first, the 2nd LAA subframes and the 3rd LAA subframes can also base Impliedly notify or configure in by the PDCCH or RRC information (parameter) for signaling or configuring.For example, terminal be based on The information that CRS mapping is relevant identifies the first LAA subframes, the 2nd LAA subframes and the 3rd LAA subframes.

In addition, terminal is by a certain subframe in the case where being identified as the 2nd LAA subframes, by next height of a certain subframe The subframe of specified quantity after frame is identified as the 3rd LAA subframes.In addition, terminal will be identified as the last of the 3rd LAA subframes Subframe next subframe after subframe be identified as before the 2nd LAA subframes, be identified as the first LAA subframes.In addition, the rule Fixed number amount (sub-frame number for being identified as the 3rd LAA subframes) can be with prespecified.The specified quantity can match somebody with somebody in LAA cells Put.The specified quantity can be notified by the channel and/or signal for being mapped to the 2nd LAA subframes.

In addition, in the 2nd LAA subframes and the 3rd LAA subframes, separately provide or be configured with PDSCH and/or EPDCCH primary sign.

In addition, in Fig. 5~Fig. 7, show and CCA is carried out in a subframe, but carry out CCA time (period) not It is defined in this.Carry out CCA time can also be directed to each LAA cells, each CCA timing, each CCA execution and become It is dynamic.For example, to carry out CCA based on the time of defined time time slot (time interval, time domain).The defined time time slot can be with Provide or configure using the time that a subframe is divided into specified quantity.The defined time slot can also utilize regulation The subframe of quantity is provided or configured.

In addition, in the present embodiment, the time for carrying out CCA can be expressed (during the time using defined time quantum Gap), the time of (can be sent) etc., the size of field in time domain are sent in a certain subframe for channel and/or signal.For example, The size of field in time domain is expressed as some time quantums Ts.Ts was 1/ (15000*2048) second.For example, subframe when Between be 30720*Ts (1 millisecond).

, can be to terminal or LAA cell configuration LAA cells in addition it is also possible to as the subframe #3 in Fig. 5~Fig. 7 The symbol of midway in a certain subframe sends channel and/or signal (including reservation signal).For example, the signaling that terminal passes through RRC The information for representing that this transmission can be carried out is configured with the configuration relevant with LAA cells.Terminal is based on the information pair and LAA Reception (monitoring, identification, decoding) relevant processing in cell switches over.

In addition, the subframe that can be transmitted from the symbol of midway also may be used (also comprising the subframe that can send symbol partway) To be all subframes in LAA cells.In addition, the subframe that can be transmitted from the symbol of midway can also be pre- to LAA cells Subframe as defined in elder generation or the subframe of configuration.

In addition, the subframe that can be transmitted from the symbol of midway also can (also comprising the subframe that can send symbol partway) Uplink based on TDD configures (UL/DL configurations) being configured, being notified or being determined.For example, this subframe is Configured by UL/DL to notify (specified) subframe for special subframe.Special subframe in LAA cells is to include DwPTS (Downlink Pilot Time Slot：Descending pilot frequency time slot), GP (Guard Period：Guard period) and UpPTS (Uplink Pilot Time Slot：Uplink pilot time slot) at least one subframe in these three fields.With in LAA cells The relevant configuration of special subframe can configure or notify by RRC signaling, PDCCH or EPDCCH signaling.The configuration For DwPTS, GP and UpPTS at least one setup time length.In addition, the configuration is to represent prespecified time length The index information of the candidate of degree.Made in addition, the configuration can use with the special subframe configuration being configured in conventional TDD cell DwPTS, GP and UpPTS identical time span.That is, the time span that can be sent in a certain subframe is based on DwPTS, GP And UpPTS any one and determine.

In addition, in the present embodiment, reservation signal can be different as the LAA cells from sending the reservation signal The signal that can receive of LAA cells.For example, the LAA cell different from sending the LAA cells of the reservation signal be with just In the adjacent LAA cells (adjacent LAA cells) of the LAA cells for sending the reservation signal.For example, the reservation signal includes and this Subframe specified in LAA cells and/or the relevant signal of the transmission situation (behaviour in service) of symbol.With send it is a certain pre- In the case that the different LAA cells of the LAA cells of about signal receive the reservation signal, the LAA for receiving the reservation signal is small Area is scheduled based on subframe and/or the transmission situation of symbol as defined in reservation signal identification according to the situation.

In addition, LBT can also be carried out before channel and/or signal is sent by receiving the LAA cells of the reservation signal. The LBT is carried out based on the reservation signal received.For example, in the LBT, consider to have sent the LAA cells institute of reservation signal The channel and/or signal of (it is assumed that send) are sent, to carry out the scheduling of the selection etc. comprising resource allocation, MCS.

In addition, transmission channel and/or signal are carried out based on the reservation signal in the LAA cells for receiving the reservation signal Scheduling in the case of, can be by defined method to including more than one including the LAA cells that have sent the reservation signal LAA cells notify the information relevant with the scheduling.For example, the defined method is to send the regulation comprising including reservation signal Channel and/or signal method.In addition, for example, the defined method is the method notified by backhauls such as X2 interface.

In addition, in carrier aggregation and/or dual link, conventional terminal can configure most 5 serving cells, but this implementation Terminal in mode can extend the maximum quantity for the serving cell that can be configured.That is, the terminal in present embodiment can configure super Cross the serving cell of 5.For example, the terminal in present embodiment can configure most 16 or 32 serving cells.For example, configuration The serving cell more than 5 of terminal in present embodiment includes LAA cells.For example, it is configured in present embodiment The serving cell more than 5 of terminal can be entirely LAA cells.

In addition, in the case where that can configure the serving cell more than 5, the configuration relevant with the serving cell of a part can It is different with the configuration with conventional serving cell (that is, conventional secondary cell).For example, on the configuration, following aspect is not Together.Configuration described below can be applied in combination.

(1) in the terminal, most 5 conventional serving cells are configured with, be configured with most 11 or 27 with the past not Same serving cell.I.e., in the terminal, in addition to conventional main plot, most 4 conventional secondary cells is also configured with, are matched somebody with somebody It is equipped with most 11 or 27 and in the past different secondary cells.

(2) configuration relevant from the past different serving cells (secondary cell) includes the configuration relevant with LAA cells.Example Such as, in the terminal, in addition to conventional main plot, most 4 is also configured with and does not include the auxiliary of the configuration relevant with LAA cells Cell, it is configured with most 11 or 27 and in the past different secondary cells.

In addition, in the case where that can configure the serving cell more than 5, base station (including LAA cells) and/or terminal can be entered The row processing or hypothesis different from the situation for configuring most 5 serving cells.For example, on the configuration or it is assumed that following aspect It is different.Processing or hypothesis described below can be applied in combination.

(1) in the terminal, in the case where being equipped with more than the serving cell of 5, also assume that from most 5 serving cells Send (reception) PDCCH, EPDCCH and/or PDSCH simultaneously.Thus, terminal can be for PDCCH, EPDCCH and/or PDSCH Receive and use method same for the HARQ-ACK of PDSCH transmission.

(2) in the terminal, in the case where being equipped with more than the serving cell of 5, it is configured with these serving cells Carry out the combination (group) of the cell of the binding of the HARQ-ACK for PDSCH.For example, all serving cells, all secondary cells, institute There are LAA cells or all bindings for including the HARQ-ACK between each serving cell respectively from the past different secondary cells Relevant information (configuration).For example, the relevant information of the binding of the HARQ-ACK between serving cell is to carry out the mark of the binding Know symbol (index, ID).For example, the identifier identical cell for stepping into the capable binding bundlees to HARQ-ACK.Pass through logic With computing to carrying out the binding as the HARQ-ACK of object.In addition, carrying out the maximum quantity of the identifier of the binding can be set to 5.In addition, the maximum quantity for carrying out the identifier of the binding includes can be set to 5 without the quantity of the cell of the binding interior. That is, the quantity maximum of the group bundled more than serving cell can be set to 5.Thus, terminal can for PDCCH, EPDCCH and/ Or PDSCH reception and for the PDSCH HARQ-ACK transmission use method same.

(3) in the terminal, in the case where being equipped with more than the serving cell of 5, it is configured with these serving cells Carry out the combination (group) of the cell of the multiplexing (multiplexing) of the HARQ-ACK for PDSCH.It is directed to being configured with In the case of the combination (group) of the cell of PDSCH HARQ-ACK multiplexing, based on the group, by PUCCH or PUSCH come The HARQ-ACK being multiplexed is transmitted., it is specified that or being configured with the serving cell of multiplexing most in each group Big quantity.The maximum quantity is provided or configures based on the maximum quantity for configuring serving cell in the terminal.For example, the maximum Quantity is the maximum of serving cell that the maximum quantity of the serving cell with being configured in terminal is identical or is configured in terminal The half of quantity.In addition, maximum of the PUCCH sent simultaneously the maximum quantity based on the serving cell multiplexed in each group The maximum quantity of quantity and the serving cell being configured in terminal is provided or configured.

In other words, the quantity of the first service cell (that is, main plot and/or secondary cell) configured be specified quantity (i.e., 5) the first service cell and the summation of the second service cell (that is, LAA cells) below, configured exceedes above-mentioned rule Fixed number amount.

Then, pair terminal capability associated with LAA illustrates.Terminal passes through RRC letter based on the instruction from base station Order gives information (terminal capability) notice (transmission) relevant with the ability of the terminal (capability) to base station.For some work( The terminal capability of energy (feature) is notified (transmission) in the case where supporting the function (feature), is not supporting the function (feature) In the case of be not notified (transmission).In addition, the terminal capability for some function (feature) can also represent that the function is (special Sign) test and/or the information whether completed of installation.For example, the terminal capability in present embodiment is as follows.End described below End ability can be applied in combination.

(1) terminal capability relevant with the support of LAA cells and have with the support of the configuration of the serving cell more than 5 The terminal capability of pass is defined independently respectively.For example, support the configuration of serving cell of the terminal-pair more than 5 of LAA cells It is supported.That is, the terminal of the configuration of the serving cell more than 5 is not supported or not LAA cells.In this case, to more than 5 The terminal that the configuration of individual serving cell is supported can be supported or not support LAA cells.

(2) terminal capability relevant with the support of LAA cells and have with the support of the configuration of the serving cell more than 5 The terminal capability of pass is defined independently respectively.For example, support the terminal-pair LAA cells of the configuration of the serving cell more than 5 It is supported.That is, the terminal of LAA cells is not supported or not the configuration of the serving cell more than 5.In this case, support LAA The terminal of cell can be supported or not support the configuration of the serving cell more than 5.

(3) terminal capability relevant with the downlink in LAA cells and relevant with the up-link in LAA cells Terminal capability is defined independently respectively.For example, in the terminal-pair LAA cells being supported to the up-link in LAA cells Downlink be supported.For example, do not support the downlink in LAA cells terminal do not support it is up in LAA cells Link.In this case, the terminal that the downlink in LAA cells is supported can be supported or do not support that LAA is small Up-link in area.

(4) terminal capability relevant with the support of LAA cells includes the support for the sending mode for being only configured at LAA cells.

(5) terminal capability relevant with the downlink in the configuration of the serving cell more than 5 and the clothes more than 5 The relevant terminal capability of up-link in the configuration for cell of being engaged in is defined independently respectively.For example, small to the service more than 5 Downlink in the configuration of serving cell of the terminal-pair that up-link in the configuration in area is supported more than 5 is propped up Hold.That is, the terminal that the downlink not in the configuration to the serving cell more than 5 is supported is not to the service more than 5 Up-link in the configuration of cell is supported.In this case, the downlink in configuration to the serving cell more than 5 The terminal being supported can be supported or not support the up-link in the configuration of the serving cell more than 5.

(6) in the terminal capability in the configuration of the serving cell more than 5, to most 16 downlink serving cells The terminal capability that the configuration of (component carrier) is supported and the configuration to most 32 downlink serving cells are supported Terminal capability be defined independently respectively.In addition, the end that the configuration to most 16 downlink serving cells is supported The configuration at least one uplink service cell is held to be supported.Configuration to most 32 downlink serving cells is entered The configuration for terminal-pair at least two uplink service cell that row is supported is supported.That is, to most 16 downlink services The terminal that the configuration of cell is supported can not also be supported to the configuration of at least two uplink service cell.

(7) terminal capability relevant with the support of LAA cells is notified based on frequency (frequency range) used in LAA cells. For example, in the notice of the combination of frequency or frequency that terminal is supported, included extremely in the combination of the frequency or frequency notified In the case of frequency used in a few LAA cell, the terminal impliedly notifies to be supported LAA cells.That is, leading to In the case that the combination of the frequency or frequency known does not include frequency used in LAA cells completely, the terminal impliedly notifies not LAA cells are supported.

Then, pair illustrated with the 2nd EPDCCH terminal capabilities associated.Terminal capability in the present embodiment In one example, with the field of the 2nd EPDCCH terminal capabilities associated can terminal be received the 2nd EPDCCH USS and/or DCI in CSS is defined.That is, should in the case of the DCI in the USS and/or CSS that the terminal can receive the 2nd EPDCCH Terminal-pair supports (supported) to be notified by the field of the terminal capability associated with the 2nd EPDCCH.In addition, at the end In the case that end can not receive the DCI in the 2nd EPDCCH USS and/or CSS, what the terminal pair did not associated with the 2nd EPDCCH The field of terminal capability is notified.

In addition, in the case of DCI in the USS and/or CSS that the terminal can receive the 2nd EPDCCH, the terminal has Receive the ability of the DCI in the first EPDCCH USS.That is, in the terminal notification by the terminal capability that is associated with the 2nd EPDCCH Field be supported (Supported) in the case of, notify to be carried out by the field of terminal capability associated with the first EPDCCH Support (Supported).In addition, it is supported in the terminal notification by the field of the terminal capability associated with the 2nd EPDCCH (Supported) in the case of, the terminal can also represent the ability with the DCI in the USS for receiving the first EPDCCH.

In addition, in the case of DCI in the USS and/or CSS that the terminal can receive the 2nd EPDCCH, the terminal also has There is the ability relevant with LAA (for example, ability comprising described above).That is, in the terminal notification by being associated with the 2nd EPDCCH Terminal capability field be supported (Supported) in the case of, notify that the field by the terminal capability associated with LAA is entered Row supports (Supported).In addition, it is supported in the terminal notification by the field of the terminal capability associated with the 2nd EPDCCH (Supported) in the case of, the terminal can represent also there is the ability relevant with LAA.

In addition, in the present embodiment, LAA cells are sent to enter the DCI of the PDSCH for being sent by the LAA cells The PDCCH or EPDCCH of row notice situation (that is, the situation of self scheduling) are illustrated, but are not limited to this.For example, The serving cell different from LAA cells send to the DCI of the PDSCH for being sent by the LAA cells PDCCH notified or In EPDCCH situation (that is, the situation of cross-carrier scheduling), the method illustrated in present embodiment can be also applied.

In addition, in the present embodiment, for identifying that the information of the symbol sent for channel and/or signal can also be based on The symbol for not supplying channel and/or signal to send.For example, the information is to represent the symbol for not supplying channel and/or signal to send most The information of symbol afterwards.In addition, for identifying that the information of the symbol sent for channel and/or signal can also be based on other information Or parameter determines.

In addition, in the present embodiment, the symbol sent for channel and/or signal can also be independently of channel and/or letter Number configure (notice, regulation).That is, information and its Notification Method energy for identifying the symbol sent for channel and/or signal Independently configured (notice, regulation) in channel and/or signal.For example, for identifying the symbol sent for channel and/or signal Number information and its Notification Method independently can configure (notice, regulation) in PDSCH and EPDCCH.

In addition, in the present embodiment, from the viewpoint of terminal, channel and/or signal is not supplied to send and (can not be sent out Send) symbol/subframe can also be set to not assume that to send the symbol/subframe of (can be sent) for channel and/or signal.That is, The terminal, which can be considered as, does not supply the LAA cells to send channel and/or signal by the symbol/subframe.

In addition, in the present embodiment, from the viewpoint of terminal, sent (can be sent) for channel and/or signal Symbol/subframe can also be set to be assumed to the symbol/subframe that may be sent for channel and/or signal.That is, can be considered as can for the terminal Can be for the LAA cells may not also be supplied to send channel and/or signal by the symbol/subframe.

In addition, in the present embodiment, from the viewpoint of terminal, sent (can be sent) for channel and/or signal Symbol/subframe can also be set to be assumed to the symbol/subframe that must be sent for channel and/or signal.That is, can be considered as must for the terminal Surely channel and/or signal are sent by the symbol/subframe for the LAA cells.

In addition, in the present embodiment, LAA cells can also be set to the serving cell using defined frequency range.

Then, to extending physical downlink control channels (EPDCCH：Enhanced Physical Downlink Control Channel) illustrate.It should be noted that EPDCCH is same with other physical channels such as PDSCH, money is used Source element (RE：Resource Element) received and dispatched.(pass through carrier wave and OFDM for antenna port P resource grid The grid of symbol describes transmitted signal according to time slot) each key element it is (corresponding with a subcarrier and an OFDM symbol Key element) it is referred to as RE, by index to, i.e. k (since 0, along the index of frequency axis direction ascending order) and l in a time slot (since 0, along the index of time-axis direction ascending order) uniquely identifies.

EPDCCH structure and/or processing can the conventional subframe of conventional cell, the part subframe of LAA cells and/or It is each different in whole subframes of LAA cells.For example, in the subframe of part, using by with conventional subframe and/or whole subframes institute The EPDCCH used is compared to the EPDCCH that less OFDM symbol is formed.In the present embodiment, used in conventional subframe EPDCCH is also referred to as the first EPDCCH, and EPDCCH used in the subframe of part is also referred to as the 2nd EPDCCH.Need what is illustrated It is that in whole subframes, the first EPDCCH and/or the 2nd EPDCCH can also be used.

Fig. 8 represents an example of the EREG structures of a RB centering.EREG (Enhanced RE Group) is used to provide Mappings of the EPDCCH to RE.Each resource block pair has 16 EREG of the numbering for imparting 0 to 15.In a PRB pair, To except carrying relative to usual CP (Cyclic Prefix：Cyclic prefix) antenna port 107,108,109 and 110 RE all beyond the RE relative to the DMRS of extension CP antenna port 107 and 108 DMRS RE and carrying, according to frequency Rate is first, time posterior ascending order circulation assigns 0 to 15 numbering.In fig. 8, the resource element that shade is got with oblique line is used for Carry DMRS.All RE for imparting numbering i in the PRB pair form the EREG for imparting i numberings.Here, CP is attached to The letter in the front in the significant character section of the OFDM symbol (being SC-FDMA symbols in the case of up-link) in downlink Number, it is that the part (being usually decline) in significant character section is replicated to obtained signal.CP length has normal length (such as relative to significant character length 2048 be sampled as 160 samplings or 144 sampling) usual CP and it is longer than usual CP (such as Relative to significant character length 2048 be sampled as 512 samplings or 1024 sampling) extension CP both.

Here, EREG structure can be set to identical, and it is unrelated with the first EPDCCH or the 2nd EPDCCH.That is, according to resource Block pair, to except carrying relative to usual CP (Cyclic Prefix：Cyclic prefix) antenna port 107,108,109 and 110 RE all beyond the RE relative to the DMRS of extension CP antenna port 107 and 108 DMRS RE and carrying, rule The EREG in the first EPDCCH or the 2nd EPDCCH is determined.Thus, in the case of DMRS structure difference, although for forming EREG RE is different, but the definition for forming EREG is identical.

As shown in Figure 8, a RB two RB to being made up of.Each RB by 7 OFDM symbols on time orientation and Resource element shown in 12 subframes in frequency direction is formed.In fig. 8, DMRS is mapped to the resource that shade is got with oblique line Element.In addition, each DMRS is made up of the orthogonal code of 2 chips, the DMRS of most 2 can carry out code division multiplexing.Antenna port 107 and 108 DMRS is the OFDM symbol numbering 5 and 6 in each time slot, is mapped to the RE that subcarrier number is 0,5 and 10.My god The DMRS of line end mouth 109 and 110 is the OFDM symbol numbering 5 and 6 in each time slot, is mapped to subcarrier number as 1,6 and 11 RE.Here, DMRS illustrated in fig. 8 can be used by establishing the DMRS associated with the first EPDCCH.

The DMRS associated a example is established with the 2nd EPDCCH can use DMRS illustrated in fig. 8.That is, with second The DMRS of EPDCCH foundation associations can be used and the structure same with the DMRS of the first EPDCCH foundation associations, but second In the case of including DMRS in the OFDM symbol that EPDCCH can not be sent, the DMRS is not sent.For example, in time slot 1 In the part subframe of OFDM symbol #0~6, the OFDM symbols that the DMRS that associate only mapped into time slot 1 are established with the 2nd EPDCCH Number #5 and 6, the OFDM symbol #5 and 6 being not mapped in time slot 0.In addition, it is being mapped with 2 OFDM of the orthogonal code of 2 chips In the case that any one OFDM symbol in symbol can not be sent, it is assumed that do not sent for the DMRS.

The DMRS associated another example is established according to used in the 2nd EPDCCH transmission with the 2nd EPDCCH OFDM symbol and determine.Specifically, according to used in the 2nd EPDCCH transmission OFDM symbol structure, respectively provide confession The RE of the DMRS associated mappings is established with the 2nd EPDCCH.The knot of OFDM symbol used in transmission for the 2nd EPDCCH Structure, the pattern of the prespecified specified quantity of energy.That is, for the structure that the DMRS associated is established with the 2nd EPDCCH, similarly can The pattern of prespecified specified quantity.

Fig. 9 be represent with Part I subframe used in the 2nd EPDCCH establish an example of the DMRS structure associated The figure of son.In fig.9, the RE that shade is got with oblique line represents to supply to establish the RE of the DMRS associated mappings with the 2nd EPDCCH.With Put untapped RE (OFDM symbol) in the transmission for the 2nd EPDCCH of RE expressions for getting shade.That is, in Fig. 9 (a), time slot 0 OFDM symbol #0 is the 2nd EPDCCH primary sign, and in Fig. 9 (b), the OFDM symbol #3 of time slot 0 is second EPDCCH primary sign, in Fig. 9 (c), the OFDM symbol #0 of time slot 1 is the 2nd EPDCCH primary sign, Fig. 9's (d) in, the OFDM symbol #0 of time slot 1 is the 2nd EPDCCH primary sign, in Fig. 9 (e), the OFDM symbol #3 of time slot 1 For the 2nd EPDCCH primary sign.As shown in figure 9, it can be respectively provided according to the 2nd EPDCCH primary sign and second EPDCCH establishes the DMRS of association structure.

Figure 10 be represent with Part II subframe used in the 2nd EPDCCH establish one of the DMRS structure associated The figure of example.In Fig. 10, the RE that shade is got with oblique line represents to supply to establish the RE of the DMRS associated mappings with the 2nd EPDCCH. The RE that shade is got with point represents untapped RE (OFDM symbol) in the 2nd EPDCCH transmission.That is, in Figure 10 (a), The OFDM symbol #6 of time slot 1 is the 2nd EPDCCH terminal, and in Figure 10 (b), the OFDM symbol #3 of time slot 1 is second EPDCCH terminal, in Figure 10 (c), the OFDM symbol #1 of time slot 1 is the 2nd EPDCCH terminal, in Figure 10 (d) in, the OFDM symbol #6 of time slot 0 is the 2nd EPDCCH terminal, in Figure 10 (e), the OFDM symbols of time slot 0 Number #4 is the 2nd EPDCCH terminal.As shown in Figure 10, can be respectively provided according to the 2nd EPDCCH terminal and the Two EPDCCH establish the DMRS of association structure.In addition, with Part II subframe used in the 2nd EPDCCH establish and associate The structure that DMRS structure can be set to the DMRS with being used in DwPTS is identical.

EPDCCH carries to dispatching distribution.Use one or more continuous ECCE (Enhanced Control Channel Element：Enhancing control channel unit) aggregate (polymerization) send an EPDCCH.Here, each ECCE by Multiple EREG are formed.For an EPDCCH ECCE quantity dependent on the form of the EPDCCH and each ECCE EREG Quantity.Local transmission and the scattered both of which that sends are supported.One EPDCCH can use the EREG and PRB pair to ECCE Map different local transmissions and disperse any of transmission.

In addition, the first EPDCCH can be directed to each EPDCCH set, local transmission and scattered transmission are configured by RRC signaling It is any.2nd EPDCCH local to all EPDCCH set regulations in advance can be sent and disperse any of transmission.For example, 2nd EPDCCH scattered to all EPDCCH set regulations in advance can be sent.

Terminal installation monitors as aftermentioned to multiple EPDCCH.It can be configured with and EPDCCH is sent for terminal installation The setting of one or two PRB pair monitored.As upper-layer configured, EPDCCH set X_mIn all EPDCCH Local send or using only scattered transmission is used only in candidate.In subframe i EPDCCH set X_mIn, EPDCCH transmission institute can profit ECCE is endowed 0 to N_ECCE,m,i- 1 numbering.Here, N_ECCE,m,iIt is subframe i EPDCCH set X_mIn EPDCCH Send the quantity for the ECCE that can be utilized.Numbering n ECCE is floor (n/ corresponding to index in the case where locally mapping N^RB _ECCE) PRB in impart (n mod N^RB _ECCE)+jN^RB _ECCEThe EREG of numbering, in the case of scattered mapping, correspond to Index as (n+j max (1, N^Xm _RB/N^ECCE _EREG))mod N^Xm _RBPRB in impart floor (n/N^Xm _RB)+jN^RB _ECCEVolume Number EREG.Here, j=0,1 ..., N^ECCE _EREG- 1, N^ECCE _EREGFor each ECCE EREG quantity.In addition, N^RB _ECCEWith 16/N^ECCE _EREGIt is equal, it is the ECCE of each PRB pair quantity.In addition, floor, mod and max are bracket function, remainder respectively Function (mod functions) and max function (max functions).It should be noted that here, to forming EPCDDH set X_mPRB To assigning 0 to N with ascending order^Xm _RB- 1 numbering.

In the first EPDCCH, N^ECCE _EREGType based on CP and subframe and determine.More specifically, in common CP and In the case of common subframe (ordinary downlink subframe), or common CP and special subframe be configured to 3,4 or 8 it is special In the case of subframe, N^ECCE _EREGFor 4.Common CP and special subframe be configured to 1,2,6,7 or 9 special subframe (that is The special subframe that DwPTS is made up of the OFDM symbol of more than 6 and less than 10) in the case of, in extension CP and common son 1,2,3,5 or 6 special subframe is configured to (that is DwPTS is by 6 in the case of frame or in extension CP and special subframe The special subframe that the individual above and the OFDM symbol of less than 10 are formed) in the case of, N^ECCE _EREGFor 8.It is it should be noted that special The details of sub-frame configuration will illustrate later.

N in the 2nd EPDCCH^ECCE _EREGAn example in, N^ECCE _EREGIt is prespecified value.For example, second N in EPDCCH^ECCE _EREG1,2,6,7 or 9 special subframe is configured to the common CP in the first EPDCCH and special subframe Situation is identical, that is, 8.In addition, for example, N in the 2nd EPDCCH^ECCE _EREGWith by a resource block to the EREG formed number Measure it is identical, that is, 16.

N in the 2nd EPDCCH^ECCE _EREGAnother example in, N^ECCE _EREGDepending on being detected (it is assumed that, monitoring) N in 2nd EPDCCH_EPDCCH(aftermentioned).Specifically, the n in the 2nd EPDCCH_EPDCCHFor situation more than specified quantity Under, N^ECCE _EREGFor 4 (or 8), in the case of smaller than the specified quantity, N^ECCE _EREGFor 8 (or 16).The specified quantity both can be with It is prespecified, it can also be configured to that cell is peculiar or terminal is peculiar by RRC signaling.For example, specified quantity and first The specified quantity used in EPDCCH is identical, that is, 104.In addition, for example the specified quantity can also with the first EPDCCH The specified quantity used is different.

In addition, it is directed to n_EPDCCHSpecified quantity can also provide or be configured with it is multiple.Specifically, in the 2nd EPDCCH In n_EPDCCHIn the case of more than first specified quantity, N^ECCE _EREGFor 4, the n in the 2nd EPDCCH_EPDCCHFor the second regulation In the case that quantity is less than the first specified quantity, N^ECCE _EREGFor 8, the n in the 2nd EPDCCH_EPDCCHLess than the second rule In the case of fixed number amount, N^ECCE _EREGFor 16.For example, the first specified quantity is identical with the specified quantity used in the first EPDCCH, Namely 104.Second specified quantity is the value smaller than the first specified quantity.

N in the 2nd EPDCCH^ECCE _EREGAnother example in, N^ECCE _EREGDepending on being detected (it is assumed that, monitoring) The quantity of OFDM symbol in 2nd EPDCCH.Specifically, the quantity of the OFDM symbol in the 2nd EPDCCH is stated number In the case of more than amount, N^ECCE _EREGIt is smaller than the specified quantity for 4 (or 8), the quantity of the OFDM symbol in the 2nd EPDCCH In the case of, N^ECCE _EREGFor 8 (or 16).The specified quantity both can also be configured to cell spy with prespecified by RRC signaling Have or terminal is peculiar.

In addition, for the quantity of OFDM symbol specified quantity can also provide or be configured with it is multiple.Specifically, The quantity of OFDM symbol in two EPDCCH be the first specified quantity more than in the case of, N^ECCE _EREGFor 4, in the 2nd EPDCCH OFDM symbol quantity for the second specified quantity less than the first specified quantity in the case of, N^ECCE _EREGFor 8, second In the case that the quantity of OFDM symbol in EPDCCH is less than the second specified quantity, N^ECCE _EREGFor 16.For example, the second specified quantity It is the value smaller than the first specified quantity.

N in the 2nd EPDCCH^ECCE _EREGAnother example in, it is same with the first EPDCCH, based on CP and subframe Type determines, but N^ECCE _EREGIt is the first EPDCCH 2 times of value.More specifically, it is (common in common CP and common subframe Downlink subframe) in the case of, or in the case where common CP and special subframe are configured to 3,4 or 8 special subframe, N^ECCE _EREGFor 8.1,2,6,7 or 9 special subframe is configured to (that is DwPTS is by more than 6 in common CP and special subframe And less than 10 OFDM symbol form special subframe) in the case of, extension CP and common subframe in the case of or 1,2,3,5 or 6 special subframe is configured to (that is DwPTS is by more than 6 and less than 10 in extension CP and special subframe OFDM symbol form special subframe) in the case of, N^ECCE _EREGFor 16.

Corresponding providing that can be to EPDCCH forms with each EPDCCH ECCE quantity (polymerization grade).In addition, This is to that respectively different in the first EPDCCH and the 2nd EPDCCH should be able to provide.

In the first EPDCCH, EPDCCH forms are with each EPDCCH ECCE quantity (polymerization grade) to that should be able to advise Shape of pledging love A and case B multiple situations.Situation A is meeting to use with the case of 1 corresponding condition of situation described later, at it Then use situation B in the case of it.Polymerization grade in situation A is 2,4,8 and 16 in the case where locally sending, and is sent scattered In the case of be 2,4,8,16 and 32.Polymerization grade in case B is 1,2,4 and 8 in the case where locally sending, in scattered hair It is 1,2,4,8 and 16 in the case of sending.That is, the polymerization grade in situation A is more than the polymerization grade in case B.Thus, even in In the case that the quantity of RE used in each EREG in EPDCCH is few, by increasing polymerization grade, it can be also directed to EPDCCH defined reception characteristic.

Quantity for specific terminal installation is n_EPDCCHIt is defined as EPDCCH set X₀(the EPDCCH of most 2 Initial EPDCCH set in set) an EPDCCH PRB pair sending and configure in, meet following (a1) to (a4) The all or part of downlink RE of benchmark quantity.

(a1) it is the part of any one in 16 EREG in the PRB pair.

(a2) it is assumed to not be used as CRS by the terminal installation.As long as here, not to CRS antenna port quantity and frequency displacement Parameter other values are provided, then (be based on using these parameters in the serving cell in being configured with PBCH identicals antenna port Frequency displacement that the antenna port quantity and physical cell identifier of configuration obtain) provide CRS position.On the contrary, in terminal installation In be the group that re-MappingQCL-ConfigID-r11 is configured with these parameters by upper-layer parameters in the case of, use the parameter Determine CRS position.

(a3) it is assumed to not be used as CSIR S by the terminal installation.Here, utilize zero energy CSIR S in the serving cell Configuration (in the case of not to the other values of configuration provides for zero energy CSIR S) and non-zero power CSIR S configuration give Go out CSIR S position.On the contrary, by upper-layer parameters it is that re-MappingQCL-ConfigID-r11 is configured with zero in terminal installation In the case of power CSIR S, CSIR S position is determined using the parameter.
